Preliminary and Provisional

ONE-CHANNEL BOOST SWITCHING REGULATOR

Features

General Description

The AAT1109A is a one-channel switching

regulator control IC incorporating a soft start

function and a short circuit protection function.

Each device consists of an on-chip voltage reference,

error amplifier, pulse width modulation controller,

under-voltage protection, soft start and short circuit

protection circuits. Switching frequencies up to

1MHz are set by an external resistor and capacitor.

Soft-start time can be implemented by the SCP

capacitor.

Additionally, a chip enable feature is provided to

power down reducing the supply current to 10uA.

With a minimum number of external components,

the AAT1109A offers a simple and cost effective

solution.
