SC4612H is a high performance synchronous buck

controller that can be configured for a wide range of

applications. The SC4612H utilizes synchronous rectified

buck topology where high efficiency is the primary

consideration. SC4612H can be used over a wide input

voltage range with output voltage adjustable within limits

set by the duty cycle boundaries.

SC4612H comes with a rich set of features such as

regulated DRV supply, programmable soft-start, high

current gate drivers, shoot through protection, R

DS-ON

sensing with hiccup over current protection.

u Distributed power architectures

u Telecommunication equipment

u Servers/work stations

u Mixed signal applications

u Base station power management

u Point of use low voltage high current applications
