Overview

SC4502/SC4502H 1.
4Amp, 2MHz Step-Up Switching Regulator with Soft-Start POWER MANAGEMENT Description 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 during start-up.
The internal switch is rated at 32V (40V for the SC4502H) making the converter suitable for high voltage applications such as Boost, SEPIC and Flyback.
