SC4508 Datasheet (Semtech Corporation) - Buck or Buck-Boost Current Mode Controller

SC4508, Buck or Buck-Boost Current Mode Controller

The SC4508 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.
