Wide Input Range High Performance Synchronous Buck Switching Controller POWER MANAGEMENT Description SC4612 is a high performance synchronous buck controller that can be configured for a wide range of applications. The SC4612 utilizes synchronous rectified buck topology where high efficiency is the primary consideration. SC4612 is optimized for applications requiring wide input supply range and low output voltages down to 500mV. SC4612 implements an asynchronous soft-start mode, which keeps the lower side MOSFET off during soft-start, a www.DataSheet4U.com desired feature when a converter turns on into a preset external voltage or pre-biased output voltage.
