Additional preview pages of the SC4508A datasheet.

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.

Wide input voltage range 2.7V to 15V Programmable output voltage Programmable switching frequency up to 1.5MHz Buck or buck boost (inverting) configuration Current mode control with slope compensation Very low quiescent current in shutdown mode Accessible reference voltage Hiccup mode after 32 cycle-by-cycle OCP 4mm x 4mm MLPQ-12 lead free package. This product is fully WEEE and RoHS compliant.
