SC4603 - High Efficiency Synchronous Buck
The SC4603 is a voltage mode step down (buck) regulator controller that provides accurate high efficiency power conversion from input supply range 2.25V 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
