AAT4900

Buffered Power Half-Bridge

™

FastSwitch

General Description

Features

The AAT4900 FastSwitch is a member of

AnalogicTech's Application Specific Power

MOSFET™ (ASPM™) product family. It is a

buffered power half-bridge, consisting of low on

resistance power MOSFETs with integrated control

logic. This device operates with inputs ranging

from 2.0V to 5.5V, making it ideal for 2.5V, 3V, and

5V systems. The device is protected from shoot-

through current with its own control circuitry. The

AAT4900 is capable of very fast switching times

and is ideal for use in high frequency DC/DC con-

verters. The quiescent supply current is a low 4mA

at 1MHz CLK frequency. In shutdown mode, the

supply current decreases to less than 1µA max.
