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.
