SC4502H 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.

SC4502H 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
