Synchronous Step-Down Controller with DDR Memory Termination
Rev. 1.0.0
GENERAL DESCRIPTION
The XRP6142 is a synchronous step down switching controller for over 15 Amps point-ofloads converters and optimized to generate and support DDR I, II and III memory voltages requirements.
Optimized to operate from standard 3.3V and 5V rails, the XRP6142 supports conversions down to 0.5V from an input voltage as low as 1V and can reach efficiencies of up to 96%. Based on a constant on-time control scheme and operating at a constant switching frequency over the whole input voltage range, it provides excellent load transient response while requiring no external pensation...
