AAT3183

300mA Inductorless Step-Down Converter

™

ChargePump

General Description

Features

The AAT3183 is a high efficiency step-down charge

pump converter providing up to 300mA of output

current. The 1/2x (gain) charge pump converter

topology provides enhanced efficiency over conven-

tional LDO regulators and requires only three low

cost ceramic capacitors. No inductor is required;

saving space and cost when compared to inductive

switching regulators.

V_INRange: 2.7V to 5.5V

V_OUT: 1.5V

300mA Maximum Output Current

Ultra-Small Solution for Portable Applications

— Small Footprint

— Only Three External Ceramic Capacitors

Required

— No Inductor

High Efficiency over the Output Current Range

Excellent Transient Performance

35µA Typical Quiescent Current

<1.0µA Shutdown Current

Up to 2MHz Switching Frequency

Integrated Soft-Start

Short-Circuit and Thermal Protection

2.0x2.1mm SC70JW-8 Package

-40ºC to 85ºC Temperature Range

•

The AAT3183 typically consumes 35µA of no load

(zero output current) quiescent current, making it

ideal for portable battery powered systems.

Shutdown current is less than 1µA.

The AAT3183 soft-start prevents excessive inrush

current while providing monotonic turn-on charac-

teristics. The device includes integrated short-cir-

cuit and over-temperature (thermal) protection to

safeguard system components.

The AAT3183 is available in a Pb-free 2.0x2.1mm

SC70JW-8 package. Operating temperature range

is -40ºC to +85ºC.
