High Density 200 A (255 A Peak) 6 Phase DC-DC Buck Converter with PMBus Interface Reference Design (PMP9738)

Advanced DCAP+ control is used to provide the high speed dynamic control needed for CPU, Memory and ASIC applications. Six high current synchronous power stages provide the high currents and low losses needed for these applications. Multi-phase also allows output ripple cancellation and effective higher bandwidth control for a given switching frequency. PMP9738 focuses on ease of electrical testing and ability to make changes "on the fly" thru the PMBus interface. On board bias supplies and a high speed dynamic load round out the rich test interface.

Возможности
