AAT1130

2.5MHz 400mA Step-Down DC/DC Converter

Features

General Description

The AAT1130 SwitchReg™ is a member of Skyworks' Total

Power Management IC™ product family. The converter

uses a predictive on-time, current-mode step-down con-

trol scheme that provides a fixed 2.5MHz switching fre-

quency (under steady state conditions). It allows the

control circuit to react nearly instantly in order to improve

transient response and to enhance stability with the LC

components as small as 1.0μH. The unique architecture

improves transient response while allowing tiny passive

LC filter components. The high switching frequency (up to

2.5MHz) keeps output voltage ripple low.

• 2.5MHz Switching Frequency

• Fast Transient Response with Small LC Output Filter

Components

• Input Voltage Range: 2.7V to 5.5V

• Output Voltage Range: 0.6V to 1.8V

• High 92% Peak Efficiency (V_IN= 3.6V, V_OUT= 1.8V)

• Low 60ꢀA Quiescent Current

• 400mA Maximum Continuous Output Current

• Internal 150μs Soft-Start Feedback Ramp

• Over-Temperature Protection

• Anti-RingingSwitchtoReduceEMIDuringDiscontinuous

Conduction Mode Operation

• Valley Current Limit Protection

• SC70JW-10 Package

• -40°C to 85°C Temperature Range

The AAT1130 delivers up to 400mA of output current,

while consuming only 60μA of quiescent current. The

AAT1130 regulates an output voltage between 0.6V and

1.8V from an input voltage of 2.7V to 5.5V. The AAT1130's

output voltage is set by an external resistive voltage

divider circuit. Internal MOSFET switches reduce the over-

all solution size while maintaining high efficiency over a

wide load current range.

Applications

• Microprocessor/DSP Core and I/O

• Mobile Phones

The AAT1130 is available in a space-saving 2.0x2.2mm

SC70JW-10 package and is rated over the -40°C to 85°C

temperature range.

• PDAs and Handheld Computers

• Digital Cameras

• Portable Music Players

• Handheld Games

• Handheld Instruments
