General Description

The AAT3190 charge pump controller provides the regu-

lated positive and negative voltage biases required by

active matrix thin-film transistor (TFT) liquid-crystal dis-

plays (LCDs), charge-coupled device (CCD) sensors, and

organic light emitting diodes (OLEDs). Two low-power

charge pumps convert input supply voltages ranging from

2.7V to 5.5V into two independent output voltages.

The dual low-power charge pumps independently regu-

late a positive (VPOS) and negative (VNEG) output voltage.

These outputs use external diode and capacitor multi-

plier stages (as many stages as required) to regulate

output voltages up to ±25V. Built-in soft-start circuitry

prevents excessive in-rush current during start-up. A

high switching frequency enables the use of small exter-

nal capacitors. The device’s shutdown feature discon-

nects the load from VIN and reduces quiescent current to

less than 1.0μA.

The AAT3190 is available in a Pb-free MSOP-8 or

TSOPJW-12 package and is specified over the -40°C to

+85°C operating temperature range.

Functional Description

Dual Charge Pump Regulators

The AAT3190 provides low-power regulated output volt-

ages from two individual charge pumps. Using a single

stage, the first charge pump inverts the supply voltage

(VIN) and provides a regulated negative output voltage.

The second charge pump doubles VIN and provides a

regulated positive output voltage. These outputs use

external Schottky diodes and capacitor multiplier stages

(as many as required) to regulate up to ±25V. A con-

stant switching frequency of 1MHz minimizes the output

ripple and capacitor size.

Negative Charge Pump

During the first half-cycle, the P-channel MOSFET turns

on and the flying capacitor C7 charges to VIN minus a

diode drop (Figure 1). During the second half-cycle, the

P-channel MOSFET turns off and the N-channel MOSFET

turns on, level shifting C7. This connects C7 in parallel

with the output reservoir capacitor C10. If the voltage

across C10 minus a diode drop is less than the voltage

across C7, current flows from C7 to C10 until the diode

turns off.

Positive Charge Pump

During the first half-cycle, the N-channel MOSFET turns

on and charges the flying capacitor C4 (Figure 2). During

the second half-cycle, the N-channel MOSFET turns off

and the P-channel MOSFET turns on, level shifting C4 by

the input voltage. This connects C4 in parallel with the

reservoir capacitor C5. If the voltage across C5 plus a

diode drop is less than the level shifted flying capacitor

(C4 + VIN), charge is transferred from C4 to C5 until the

diode turns off.

Voltage Reference

The voltage reference is a simple band gap with an out-

put voltage equal to VBE + K*VT

. The band gap reference

amplifier has an additional compensation capacitor from

the negative input to the output. This capacitor serves to

slow down the circuit during startup and soft starts the

voltage reference and the regulator output from over-

shoot. The reference circuit amplifier also increases the

overall PSRR of the device. An 80k resistor serves to

isolate and buffer the amplifier from a small internal filter

capacitor and an optional large external filter capacitor.

Enable and Start-up

The AAT3190 is disabled by pulling the EN pin low. The

threshold levels lie between 0.5V and 1.5V. Even though

the quiescent current of the IC during shutdown is less

than 1μA, the positive output voltage (VOP) and any load

current associated with it does not disappear without the

complete removal of the input voltage. This is due to the

fact that with no switching of the DRVP pin, the input

voltage simply forward biases the Schottky diodes asso-

ciated with the VOP charge pump, providing a path for

load current to be drawn from the input voltage.

Depending on the application, the supplies must be

sequenced properly to avoid damage or latch-up. The

AAT3190 start-up sequence ramps up the VOP output

200μs after the VON output is present. The AAT3190-1

ramps up the positive supply before the negative supply.

Over-Temperature Protection

A logic control circuit will shut down both charge pumps

in the case of an over-temperature condition.

Under-Voltage Lockout

A UVLO circuit disables the AAT3190 when the input volt-

age supply is lower than 1.8V nominal.

Design Procedure

and Component Selection

Output Voltage

The number of charge pump stages required for a given

output varies with the input voltage applied. The number

of stages required can be estimated by:

VOP - VIN

VIN - 2VF

np =

for the positive output and

VON

2VF - VIN

nn =

for the negative output.

When solving for np and nn, round up the solution to the

next highest integer to determine the number of stages

required.

VON

The negative output voltage is adjusted by a resistive

divider from the output (VON) to the FBN and REF pin.

The maximum reference voltage current is 50μA; there-

fore, the minimum allowable value for R2 of Figure 1 is

24k. It is best to select the smallest value possible for

R2, as this will keep R1 to a minimum. This limits errors

due to the FBN input bias current. The FBN input has a

maximum input bias current of 100nA. Using the full

50μA reference current for programming VON:

VREF

IPGM = = = 50μ

will limit the error due to the input bias current at FBN

to less than 0.2%:

With R2 selected, R1 can be determined:

R1 =

VOP

The positive output voltage is set by way of a resistive

divider from the output (VOP) to the FBP and ground pin.

Limiting the size of R4 reduces the effect of the FBP bias

current. For less than 0.1% error, limit R4 to less than

12k.

Flying and Output Capacitor

The flying capacitor minimum value is limited by the

output power requirement, while the maximum value is

set by the bandwidth of the power supply. If CFLY is too

small, the output may not be able to deliver the power

demanded, while too large of a capacitor may limit the

bandwidth and time required to recover from load and

line transients. A 0.1μF X7R or X5R ceramic capacitor is

typically used. The voltage rating of the flying and res-

ervoir output capacitors varies with the number of

charge pump stages. The reservoir output capacitor

should be roughly 10 times the flying capacitor. Use

larger capacitors for reduced output ripple.

Positive Output Capacitor

Voltage Ratings

The absolute steady-state maximum output voltage

(neglecting the internal RDS(ON) drop of the internal

MOSFETs) for the nth stage is:

VBULK(n) = (n + 1) · VIN - 2 · n · VFWD

where VFWD is the estimated forward drop of the Schottky

diode. This is also the voltage rating required for the nth

bulk capacitor in the positive output charge pump.

The voltage rating for the nth flying capacitor in the

positive stage is:

VFLY(n) = VBULK(n + 1) - VFW

where VBULK(0) is the input voltage (see Table 1).

Single Output Operation

If only one of the two channels is needed, it is possible

to disable either output. Connect the respective FB pin to

VIN to disable the output (e.g., connect FBN to VIN in

order to disable the negative output).

Input Capacitors

Input Capacitor

The primary function of the input capacitor is to provide a

low impedance loop for the edges of pulsed current drawn

by the IC. A low ESL X7R or X5R type ceramic capacitor

is ideal for this function. The size required will vary

depending on the load, output voltage, and input voltage

characteristics. Typically, the input capacitor should be 5

to 10 times the flying capacitor. If the source impedance

of the input supply is high, a larger capacitor may be

required. To minimize stray inductance, the capacitor

should be placed as closely as possible to the IC. This

keeps the high frequency content of the input current

localized, minimizing radiated and conducted EMI.

Rectifier Diodes

For the rectifiers, use Schottky diodes with a voltage rat-

ing of 1.5 times the input voltage. The maximum steady-

state voltage seen by the rectifier diodes for both the

positive and negative charge pumps (regardless of the

number of stages) is:

VREVERSE = VIN - VF

The BAT54S dual Schottky is offered in a SOT23 package

that provides a convenient pin-out for the voltage dou-

bler configuration. The BAT54SDW quad Schottky in a

SOT363 (2x2mm) package is a good choice for multiple-

stage charge pump configuration (see Figure 3, Evaluation

Board Schematic).

PC Board Layout

The input and reference capacitor should be placed as

close to the IC as possible. Place the programming resis-

tors (R1-R4) close to the IC, minimizing trace length to

FBN and FBP. Figures 4 and 5 display the evaluation

board layout with the TSOPJW-12 package.
