XRP6142 Synchronous Step-Down Controller with DDR Memory Termination
The XRP6142 is a synchronous step down switching controller for over 15 Amps point-of-loads 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. 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 compensation components and comes in three selectable on-time options(0.5µs, 1µs and 2µs). The XRP6142 easily generates VDDQ (VDD) or VTT voltages while an on board buffer provides the buffered VTT reference voltage. The XRP6142 is available in a compact RoHS compliant “green”/halogen free 16-pin QFN package.
