DATA SHEET

AAT2511

Dual 600mA, 1MHz Step-Down DC/DC Converter

Features

General Description

•

The AAT2511 is a member of Skyworks' Total Power

Management IC (TPMIC™) product family. It is com-

prised of two 1MHz step-down converters designed to

minimize external component size and cost. The input

voltage ranges from 2.7V to 5.5V. The output voltage

ranges from 0.6V to the maximum applied input voltage

and is externally adjustable.

Up to 97% Efficiency

25μA Quiescent Current Per Channel

V_INRange: 2.7V to 5.5V

V_OUTRange: 0.6V to V_IN

Output Current: 600mA

Low R_DS(ON)0.4 Integrated Power Switches

Low Drop Out 100% Duty Cycle

1.0MHz Switching Frequency

Shutdown Current <1μA

Current Mode Operation

Internal Reference Soft Start

Short-Circuit Protection

Peak current mode control with internal compensation

provides a stable converter with low ESR ceramic output

capacitors for extremely low output ripple. Each channel

has a low 25μA quiescent operating current, which is

critical for maintaining high efficiency at light load.

Fast Turn-On (100μs Typical)

Over-Temperature Protection

3mm x 3mm, < 1mm high

TDFN33-12 Package

For maximum battery life, each converter’s high-side

P-channel MOSFET conducts continuously when the

input voltage approaches dropout (100% duty cycle

operation).

-40°C to +85°C Temperature Range

Both regulators have independent input and enable

inputs.

Applications

The AAT2511 is available in a Pb-free, thermally-

enhanced 12-pin TDFN33 package, and is rated over the

-40°C to +85°C temperature range.
