AAT2614

Step-Down DC/DC Converter with Quad High PSRR LDOs

Features

General Description

•

The AAT2614 is a multiple rail power management IC. It

integrates a 600mA high-frequency switching-converter

and four 300mA linear regulators. The switching power

supply is a highly-integrated monolithic step-down con-

verter operating at 1.7MHz, achieving high efficiency with

small external components. The four linear regulators are

high PSRR low dropout regulators (LDOs) providing accu-

rate regulation and excellent transient response.

Current Mode Control DC/DC Converter:

Fixed Factory Programmable Output Up to 600mA

 1.7MHz Switching Frequency

 Up to 90% Efficiency

 Integrated Switching Power FETS

▪

 Integrated Compensation Network

▪

 Internal Current Limit

▪

•

4 Low Dropout Regulators with Separate Enable Pins:

 300mA per Channel

 High PSRR

 Factory Programmable Output

▪

The step-down converter and the four LDOs are all fixed

voltage outputs of seven combinations for 1V, 1.2V, 1.3V,

1.8V, 2.8V, 3.0V and 3.3V. Integrated over-current or

over-temperature protection circuitry becomes active

when overload or over-temperature fault occurs and the

AAT2614 recovers automatically when the fault is

removed.

▪

•

Integrated Soft-Start

Over-Current Protection

Over-Thermal Protection

TQFN33-20 and WLCSP-16 Packages

The AAT2614 is available in a Pb-free, thermally enhanced

20-pin TQFN33 package and a 16-bump 0.4 pitch CSP

package.
