SC4502H: 1.4 Amp, 2 MHz Step-Up Switching Regulator with Soft-Start
The 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.
