SC4501 - 2MHz Step-Up Switching Regulator
The SC4501 is a high-frequency current-mode step-up switching regulator with an integrated 2A 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
