Product Summary
The AAT1109-S-T is a one-channel step-up PWM controller incorporating a soft-start and a short circuit protection (SCP) function. The AAT1109-S-T consists of an on-chip voltage reference, error amplifier, pulse width modulation controller, under-voltage lockout protection, soft-start, and short circuit protectiocircuits. Switching frequency up to 1MHz is set by an external resistor and capacitor. Soft-start time can be implementedby the SCP capacitor.
