NEW PROD UCT
Transition Mode PFC LED Controller
Description
The AL6562A is a current mode Power Factor Correction Controller
and is designed for operating in Transition Mode. With a superior
linear performance multiplier, it ensures the device operates over a
wide input voltage range with superior THD (Total Harmonics
Distortion). The output voltage is controlled by means of an error
amplifier and a precise (1% @ TJ = +25°C) internal voltage reference.
The AL6562A is designed to meet stringent energy-saving standards
with low start-up current, and can operate with low current
consumption when entering stand-by mode.
OVP circuitry increases system robustness, allowing the device to
withstand transient caused at start-up and during load-disconnects.

Pin Descriptions
Pin Number
Pin Name
Brief Description
1
INV
Inverting Input Pin of the Internal Error Amplifier.
This pin is connected externally via a resistor divider from the regulated output voltage. It can provide
input to inverting input of internal error amplifier. This pin can also be used as ENABLE/DISABLE
control input.
2
COMP
Output from Error Amplifier.
A feedback compensation network consisting of resistor and capacitor connects between INV (Pin1)
and this pin to reduce the bandwidth and achieve stability of the voltage control loop and ensure high
power factor and low THD.
3
MULT
Input to the Internal Multiplier.
This pin connects to the rectified mains voltage through external resistor divider to provide a sinusoidal
voltage reference for the control current loop.
4
CS
Current Sense Connecting to External Resistor for Current Feedback.
The current flowing in the MOSFET is sensed through a resistor, the resulting voltage is applied to this
pin and compared with an internal sinusoidal-shaped reference generated by the multiplier to determine
MOSFET’s turn-off. This pin has an internal Leading-Edge-Blanking of about 200 nanoseconds to
improve noise immunity.
5
ZCD
Zero Current Detection.
This pin takes input from inductors demagnetization sensing to achieve zero current detection, required
for Transition Mode (TM) operation. A negative-going edge triggers turn-on of MOSFET.
6
GND
System Ground.
Ground for circuit. Current return for both the signal circuitry and the gate drive stage.
7
GD
Gate Driver Output.
This pin is able to drive external MOSFET. The totem-pole output stage is able to drive MOSFET with a
peak current of 600mA/800mA for source and sink capability respectively. The high level voltage of this
pin is internally clamped at about 12V to avoid excessive gate voltage in case VCC pin is supplied by a
higher voltage.
8
VCC
System Power Input Pin.
This pin is for supply voltage of both the signal part and gate driver of the IC. Upper limit is extended to
a maximum of 22V to provide more headroom for supply voltage changes. This pin has an internal 25V
Zener to protect the IC itself from overvoltage transients.

POWER FACTOR CORRECTION
AL6562A functions as a transition mode PFC IC, meaning the MOSFET turns on when inductor current reaches zero, and turns off when the
current meets desired input current reference voltage, as shown in Figure 3. A typical current waveform is depicted with envelope as shown,
with the input current following that of the input voltage, achieving good power factor.

Where  and  are the RMS (Root Mean Square) value n-th fundamental component of the current respectively. If the current and


ZCD (Zero Current Detection)
The ZCD feature detects when the transformer primary current falls to zero, as the voltage across the inductor reverses, to initiate a new cycle
that switches on the power MOSFET. The signal for ZCD is obtained by an auxiliary winding on the boost inductor, as shown in Figure 2.
Multiplier
The internal multiplier takes two inputs, one from a portion of the instantaneous rectified line voltage (via pin 3, MULT) and the other from the
output of the E/A (via pin 2, COMP), to feed the PWM comparator to determine the exact instant when the MOSFET is to be switched off. The
output of multiplier is a rectified sinusoid, similar to the instantaneous rectified line voltage, multiplied by the scaling factor determined by
output of the Error Amplifier. The MULT output is then fed into the PWM comparator and is compared to the current sense voltage VCS, to
switch the Power MOSFET off. The formula governing all parameters is given by:
Multiplier Output:

Where: k is the multiplier gain. VMULT is set by external resistors R1 and R2.
OVP (Output Overvoltage Protection)
The output voltage can be kept constant by the operation of the PFC circuit close to its nominal value, as shown by Figure 2, which is set by
the ratio of the two external resistors R3 and R4. Neglecting ripple current, current flowing through R3, IR3, will equal the current through R4,
IR4. As the non-inverting input of the error amplifier is biased inside the AL6562A at 2.5V, the current through R4 is:

 
(1)
If any abrupt change of output voltage, ΔVO > 0 occurs due to a load drop, the voltage at pin INV will be kept at 2.5V by the local feedback of
the EA. The network connected between INV and COMP introduces a time constant to achieve high PF. The current through R4 will remain
equal to 2.5/R4, but IR3 will become:

COMP. The AL6562A monitors the current flowing into the error amplifier output pin. When the detected current is higher than 40µA, the
dynamic OVP is triggered. The IC will be disabled and the driver signal will be stopped.
The output ΔVo that is able to trigger the Dynamic OVP function is then:

Application Information (cont.)
On the other hand, when the loading of PFC pre-regulator becomes low, the output voltage tends to stay steadily above the nominal value,
which is not the case when OVP is triggered by abrupt voltage increase. If this occurs, the E/A will saturate low, the external power transistor
is switched OFF, and the IC is put in idle state (static OVP). Normal operation is resumed as the error amplifier goes back into its linear region.
As a result, the device will work in burst-mode, with a repetition rate that can be very low. When either OVP is activated, the quiescent
consumption of the IC is reduced to minimum by the discharge of the capacitor and increases the hold-up capability of the IC supply.
THD (Total Harmonics Distortion)
The AL6562A reduces the THD by reducing conduction dead-angle occurring to the AC input current near the zero-crossings of the line
voltage.
The important reason for this distortion to take place is the inability of the system to transfer energy effectively when the instantaneous line
voltage is very low, which is the case near line-voltage zero-crossing. This effect is magnified by the high-frequency filter capacitor placed after
the bridge rectifier, which retains some residual voltage that causes the diodes of the bridge rectifier to be reverse-biased and the input current
flow to temporarily stop.
To overcome this issue, the circuit section designed in the AL6562A forces the PFC regulator to process more energy near the line voltage
zero-crossings, as compared to that commanded by the control loop. This results in both minimizing the time interval when energy transfer is
lacking, and fully discharging the high-frequency filter capacitor after the bridge.
In essence, the circuit artificially increases the ON-Time of the Power Switch with a positive offset added to the output of the multiplier in the
proximity of the line voltage zero-crossings. This offset is reduced as the instantaneous line voltage increases, so that it becomes negligible as
the line voltage moves towards the peak of the sinusoidal waveform.
Therefore, to maximize the benefit from the THD improvement circuit, the high-frequency filter capacitor after the bridge rectifier should be
minimized and kept to satisfy the EMI filtering requirements.
Non-Latched IC Disable (Enable)
Pin 1, INV, inverting input to the error amplifier, doubles its function as a not-latched IC disable: a voltage below 0.3V shuts down the IC and
reduces its consumption at a lower value. In order to restart the system, a voltage exceeding 0.48V must be applied. The main usage of this
function is a remote ON/OFF control interface that can be driven by a PWM controller for power management purposes. However it also offers
a certain degree of additional safety since it will make IC shutdown in case the lower resistor of the output divider is shorted to ground or if the
upper resistor is missing or fails open.

Application Information (Cont.)
Single Stage LED Driver with PFC
One of the major applications of AL6562A is to provide a single stage power module with high PF for LED lighting. The following circuit, Figure
4, shows a simplified fly-back AC-DC converter with both CC and CV feedback from output side, to prevent overload and also provide an over-
voltage protection facility.
Figure 4 Single Stage PFC Isolated LED lighting
With its high performance, the AL6562A offers the following advantages that make this solution an appropriate method against the traditional
PWM controller, where a good PF value is required:
The input capacitance can be reduced to replace a bulky and expensive high-voltage electrolytic capacitor (as required by regular
offline SMPS) by a small-size, cheaper film capacitor.
Transition mode ensures low turn-on losses in MOSFET and higher efficiency can be achieved.
Lower parts count means lower material cost, as well as lower assembly cost for limited space.

PFC Pre-Regulator
Another major application of AL6562A is to implement a wide-range mains input PFC pre-regulator, which acts as the input stage for the
cascaded DC-DC converter and can deliver above 350W in general.
The AL6562A can easily be implemented as PFC pre-regulator basing on fixed ON time mechanism due to its simplicity.
In fixed ON time mode, AL6562A is also working in transition mode where the inductor current will be turned on when zero crossing is
detected.
By using boost-switching technique, the AL6562A shapes the input current by drawing a quasi-sinusoidal current in-phase with the line voltage.
A simplified circuit, shown in Figure 5, explains the operation as follows:
Figure 5 ZCD Pin Synchronization without Auxiliary Winding
The AC mains voltage is rectified by a diode bridge and delivered to the boost converter which boosts the rectified input voltage to a higher
regulated DC bus VO.
The error amplifier compares a portion of the output voltage with an internal reference and generates a signal error proportional to the
difference between them. The bandwidth of the internal error amplifier is set to be narrow within 20Hz; the output would be a DC value over a
given half-cycle. Output of E/A fed into multiplier, multiplied by a portion of the rectified mains voltage, will generate a scaled rectified sinusoid
whose peak amplitude depends on the rectified mains peak voltage as well as the value of error signal.
The output of the multiplier is fed into the non-inverting pin of the internal PWM comparator. As the output from the multiplier, a sinusoidal
reference for PWM, equals the voltage on the current sense pin CS(4), the MOSFET will be turned off. As a consequence, the peak inductor
current will follow the envelope of a rectified sinusoid. After the MOSFET is turned off, the boost inductor discharges its stored energy to the
load until zero current is detected and then the MOSFET will be turned on again.
In the case where there is no auxiliary winding on the boost inductor, a solution can be implemented by sconnecting the ZCD pin to the drain
of the power MOSFET through an R-C network: in this way the high-frequency edges experienced by the drain will be transferred to the ZCD
pin, hence arming and triggering the ZCD comparator.
The resistance value must be properly chosen to limit the current sourced/sunk by the ZCD pin. In typical applications with output voltages
around 400V, recommended values for these components are 22pF (or 33pF) for CZCD and 330K for RZCD. With these values proper
operation is ensured even with a few volts difference between the regulated output voltage and the peak input voltage.
