SC4601 - Step Down Controller
The SC4601 is a voltage mode step down (buck) regulator controller that provides accurate high efficiency power conversion from input supply range 2.75V to 5.5V.
A high level of integration reduces external component count and makes it suitable for low voltage applications where cost, size and effic
