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.
