SC4502 2MHz Step-Up Switching Regulator

The SC4502/SC4502H is a high-frequency current-mode step-up switching regulator with an integrated 1.4A power transistor. Its high switching frequency (programmable up to 2MHz) allows the use of tiny surface-mount external passive components. Programmable soft-start eliminates high inrush current du.

SC4502 Features

* Low saturation voltage switch: 210mV (250mV for the SC4502H) Constant switching frequency current-mode control Programmable switching frequency up to 2MHz Soft-Start function Input voltage ranges from 1.4V to 16V Output voltage up to 32V (40V for the SC4502H) Low shutdown current Adj
