Overview

Low Input, High Efficiency Synchronous, Step Down Controller POWER MANAGEMENT Description The SC4605 is a voltage mode step down (buck) regulator controller that provides accurate high efficiency power conversion from a input supply range of 2.
8V to 5.
5V.
A high level of integration reduces external component count, and makes it suitable for low voltage applications where cost, size and efficiency are critical.
The SC4605 drives external N-channel MOSFETs with 1A peak current.
A non-overlap protection is provided for www.
DataSheet4U.
com the gate drive signals to prevent shoot through of the MOSFET pair.
The voltage drop across the high side MOSFET during its conduction is sensed for lossless...
