PIN CONFIGURATION

Additional voltage options are available.

DETAILED PIN DESCRIPTION

COMP

COMP is the output of the Voltage Error Amplifier (VEA). The

VEA is a low output impedance operational amplifier,

providing the input to the PWM cycle-by-cycle current limit

comparator. As the SiP280X series of parts use a true

operational amplifier for the VEA, the COMP terminal can

both source and sink current. To add flexibility to these parts,

the VEA is internally current limited, which allows OUT to be

forced to zero duty cycle by taking the COMP pin to GND.

The voltage on COMP is passed through an internal diode to

develop an offset voltage of approximately 0.6 V, and then

through a resistive divider with a gain of 0.606 V/V, before

being presented to the control input of the cycle-by-cycle

current limit comparator. Clamping the COMP pin to less

than the diode’s forward voltage (i.e., < 0.5 V) will command

the current loop to deliver 0 A, by holding the control input of

the cycle-by-cycle current comparator at 0 V. Similarly, the

current loop will command the maximum inductor current on

each cycle when COMP is at 2.25 V or greater, which drives

the control input of the cycle-by-cycle current comparator to

1 V (since [2.25 V - 0.6 V] x 0.606 V/V = 1 V).

The SiP280X series additionally features a built-in soft-start

function, which functions by clamping the output level of the

VEA to an internally generated voltage. This clamp will hold

COMP at a low voltage (VCOMP 0 V) until VCC and VREF are

at their proper levels. When these levels are appropriate for

circuit operation, the internal voltage will begin rising, at the

rate of 1 V/ms. This rising clamp level allows the voltage on

the COMP pin to rise, which in turn allows the voltage at the

control input of the cycle-by-cycle current comparator to

increase. The maximum soft-start interval occurs under

conditions requiring full duty cycle (50 % or 100 %,

depending upon the part type), and is given by the time

required for the voltage on the cycle-by-cycle current

comparator’s control input to reach 1 V. Since 1 V at the

control input to the comparator requires that the COMP pin

be at 2.25 V, the maximum soft-start interval is

approximately 2.25 ms.

Input to both the cycle-by-cycle and overcurrent fault current

sense comparators. The cycle-by-cycle current limit

comparator is the mechanism by which the VEA’s output

voltage commands the level of inductor or transformer

current during a given "on" interval, thereby regulating the

overall circuit’s output.This comparator forms the inner loop

of the two loops used in current-mode regulation.

The overcurrent comparator has a trip threshold that is 50 %

higher than that of the cycle-by-cycle comparator. Under

normal operating conditions, this comparator will not trip: its

purpose is to provide enhanced protection of the power path

components during severe faults (e.g., a short circuit). If the

overcurrent comparator is tripped by a fault condition, it will

command the SiP280X to do a "full-cycle restart". During this

restart, the power supply will be quickly driven to the "off"

state, and will be required to wait for five milliseconds

(typical) before restarting. When the supply does restart, it

will do so using the built-in soft-start function of the SiP280X.

This datasheet is subject to change without notice.

THE PRODUCT DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000

The SiP280X family incorporates internal leading-edge

blanking on the CS pin, to keep any spurious voltages on the

CS pin from reaching the comparator inputs during the

100 ns interval immediately following the rising edge on OUT

(for example, voltages due to capacitive charging currents).

Because of this internal leading-edge blanking, many

applications require no external RC filter on the CS input.

Compared to circuits requiring the use of an external RC filter

circuit, leading-edge blanking provides a shorter effective CS

to OUT propagation delay.

FB is the inverting input of the VEA. Internally compared

against VREF/2 appearing on the VEA’s non-inverting input.

To avoid stability problems, keep lead lengths to FB as short

as possible, and use good layout practices to minimize the

stray capacitances of components connected to this pin.

GND

The GND pin is both the reference ground and the power

ground for this part.

OUT

OUT is the output of a high-current driver capable of peak

currents in excess of ± 750 mA. OUT is therefore well suited

to driving the gates of power MOSFETs. This pin is

specifically held low when VCC is below the SiP280X’s UVLO

threshold, to ensure a predictable system turn-on. Since the

OUT pin is internally connected to a low impedance CMOS

buffer, it is capable of rapid rail-to-rail transitions. This output

topology also mitigates the effects of undershoot and

overshoot. For this reason, external Schottky clamp diodes

are generally not required on this pin.

RC is the oscillator frequency programming pin. FOSC is set

by the combination of RT and CT. The charging current for CT

is provided through RT, which is normally connected

between REF and the SiP280X RC pin. CT then connects

from RC to GND. Due to the high impedances encountered

in low power control circuits, this connection must be a short

and quiet return to GND (preferably by means of a dedicated

signal trace, separated from all other circuit functions).

The oscillator frequency for the SiP280X family of parts is

approximated by the following formulas:

For the SiP2800, SiP2801, SiP2802, and SiP2804:

•F

OSC  (1.5)/RTCT

For the SiP2803 and SiP2805:

•F

OSC  (1.0)/RTCT

Here RT is in ohms and CT is in farads.

More accurate formulas for FOSC are:

For the SiP2800, SiP2801, SiP2802 and SiP2804:

•F

OSC = 1/{[(CT + CSTRAY) x RT x 0.652] + [(CT + CSTRAY)

x RDISCH x 2.53] + TDELAY}

For the SiP2803 and SiP2805:

•F

OSC = 1/{[(CT + CSTRAY) x RT x 0.93] + [(CT + CSTRAY)

x RDISCH x 2.53] + TDELAY}

Here RT is in ohms and CT is in farads, RDISCH is the value

of the resistor through which CT is discharged (normally an

on-chip 130  resistor, unless the circuit is configured with

additional external discharge-path resistance), and tDELAY is

an inherent internal comparator delay time of 100 ns. The

capacitance associated with the RC pin is approximately

7.5 pF, and should be included as a part of CSTRAY.

Note that the SiP2801, SiP2804, and SiP2805 have an

internal toggle flip-flop at the output of the oscillator, to

ensure that the output duty cycle never exceeds 50 %. This

divides the frequency appearing at the OUT pin to one-half

of the oscillator frequency for these three parts.

Values of RT below 10 k are not recommended. Low values

of RT cause high circuit operating currents, and very low

values will prevent the oscillator from properly discharging

CT.

REF

The reference generator block of the Si280X provides an

accurate and stable 4.0 V or 5.0 V (depending upon part

number), which is available at this pin of the IC. This voltage

is also used internally for other functions on the IC. One of

these uses is as the logic power supply for high speed

switching logic on the IC; this, and stability concerns, make it

important to bypass VREF to GND with a good quality 0.1 µF

ceramic capacitor, as close to the part as possible. An

electrolytic or tantalum capacitor may be used in addition to

the ceramic capacitor. When 1 V < VCC < the UVLO

threshold, REF is pulled to ground through a 5 k resistor.

Hence, REF can also be used as an output to indicate the

part’s VCC status.

VCC

VCC is the positive power connection for the SiP280X

controller IC, and should be the most positive terminal on the

part. In normal operation, VCC is powered through a current

limiting resistor. The required start-up supply current will

generally be on the order of 100 µA with VCC below the

UVLO voltage of the SiP280X, and can remain at or below

500 µA total supply current once the part starts switching.

To prevent the IC from being damaged by overvoltage

conditions, each of the SiP2800 family of parts has an

internal clamp (effectively a 13.5 V Zener diode) between

VCC and GND. If the part’s VCC pin is current-fed through an

appropriate dropping resistor, the VCC pin will never exceed

its rated voltage, nor will the device as a whole exceed its

rated power dissipation. This does require knowing what the

operating current of the IC will be, so that the value of the

dropping resistor can be calculated. A good estimate of the

actual operating current (ICC) may be made by summing

three components:

(a) Any external current loading on the VCC or REF pins

(b) The operating current required by the IC itself, and

power switch.

Item (a) in the above list is a static dc value, and can

generally be calculated with good accuracy. Item (b) will

increase with operating frequency, but will be fixed for a

given value of FOSC. Item (c) is usually the dominant term in

the calculation of ICC, as the power required to drive the

external power switch will typically increase as FOUT is

increased. The most common example of this is seen in

driving the gate of a power MOSFET. In such applications,

the gate capacitances must be charged once each switching

cycle. This calculation is simplified by using the gate charge

term given by most MOSFET manufacturers, allowing the

use of the formula:

IDRIVE = FOUT x Qg of the chosen MOSFET.

A first approximation of the necessary dropping resistor

value is then given by:

R = [(Nominal VSUPPLY) - 12 V]/(Nominal ICC)

Here R is in ohms and ICC is in amperes.

The resistor limiting the current into the VCC pin should be

selected such that ICC(min) equals the worst-case maximum

sum of the above currents, while holding ICC(max) to as low a

value above that number as practicable (for best overall

efficiency), and nevermore than 25 mA above that number

(to avoid exceeding the IC’s internal clamp diode ratings).

VCC must be bypassed to GND with a good quality 0.1 µF

ceramic capacitor, as close to the part as possible. This will

help avoid problems created by high-frequency noise on the

power supply of the part. An electrolytic or tantalum capacitor

may be placed in parallel with the ceramic capacitor if more

capacitance is needed or desired.
