SC4601
SC4601 is Step Down Controller manufactured by SEMTECH.
Low Input, High Efficiency Synchronous, Step Down Controller
POWER MANAGEMENT Description
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 ponent count and makes it suitable for low voltage applications where cost, size and efficiency are critical.
Features
