SC4508A Datasheet Buck Or Buck-boost Current Mode Controller

Manufacturer: SEMTECH

Overview: Buck or Buck-Boost (Inverting) Current Mode Controller POWER.

General Description

The SC4508A is a low voltage current mode switching regulator controller that drives a P-channel power MOSFET with programmable switching frequency.

It can be configured in either buck or buck boost (inverting) converters.

The converters can be operated from 2.7V to 15V input voltage range.
