General Description

The AAT1110 is a one-channel step-down PWM

controller incorporating a soft-start function and a

short circuit protection (SCP) 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 enabled feature is provided to

power down and reduce the supply current to 10 µA .

With an optimized number of external components,

the AAT1110 offers a simple and cost effective

solution.
