SC4603
SC4603 is High Efficiency Synchronous Buck manufactured by SEMTECH.
Very Low Input, MHz Operation, High Efficiency Synchronous Buck
POWER MANAGEMENT Description
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 ponent count and makes it suitable for low voltage applications where cost, size and efficiency are critical. The SC4603 drives external plementary power MOSFETs; P-channel on the high side and N-channel on .. the low side. The use of high side P-channel MOSFETs eliminates the need for an external charge pump and simplifies the high side gate driver. Non-overlap protection...
