■OVERVIEW
AA18375AP
Switching Regulator Controller
The AA18375AP is a two-channel PWM DC-DC converter control IC that features low-voltage operation.
This IC can obtain the step-up, step-down and inverting voltages with a small number of external
components. Because the IC is compactly packaged, it is best suited for use as a power supply in
portable equipment.
