4.5A PMIC Solution for 12V Adapter Systems with 2-Output High Performance Step-Down Converters

General Description

Features

•

The AAT2688 provides two independently regulated DC

outputs: a high voltage synchronous step-down (Buck)

regulator and a low input voltage step-down low dropout

(LDO) regulator. The PMIC is optimized for low cost 12V

adapter inputs, making the device the ideal system-on-

a-chip power solution for consumer communications

equipment.

2-Output Step-Down Converters:

Channel 1 (Buck): V_IN1= 6.0 to 24.0V

V_OUT1Adjustable from 0.8V to 5.5V

I_OUT1up to 4.5A

High Switching Frequency

Voltage Mode Control

High Accuracy ±1.5%

PWM Fixed Frequency for Low Ripple

▪

Channel 1 is a step-down regulator with an input voltage

range of 6.0V to 24V, providing up to 4.5A output cur-

rent. 490kHz fixed switching frequency allows small L/C

filtering components. Channel 1 utilizes voltage mode

control configured for optimum performance across the

entire output voltage and load range.

•

Channel 2 (LDO): V_IN2= 2.7V to 5.5V

I_OUT2up to 600mA

1V Dropout Voltage at 600mA I_OUT

Ultra-small External L/C

Shutdown Current <35μA

Independent Enable Pins

Over-Current and Over-Temperature Protection

Internal Soft Start

Channel 2 is a low-dropout (LDO) regulator providing up

to 600mA output current. The device provides low out-

put noise, low quiescent current, and excellent transient

response.

4x5mm 24-Pin TQFN Low Profile Package

-40°C to 85°C Temperature Range

The step-down regulator includes integrated over-cur-

rent, soft-start and over-temperature protection. Inde-

pendent input and enable pins provide maximum design

flexibility.

Applications

The AAT2688 is available in the Pb-free 4mm x 5mm

24-pin TQFN package. The rated operating temperature

range is -40°C to 85°C.
