SC4608 - High Efficiency Synchronous Buck
The SC4608 is a voltage mode step down (buck) regulator controller that provides accurate high efficiency power conversion from an input supply range of 2.7V to 5.5V.
A high level of integration reduces external component count, and makes it suitable for low voltage applications where cost, size and
