Advanced DCAP+ control is used to provide the high speed dynamic control needed for CPU, Memory and ASIC applications. Up to 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.
PMP10393 has same hardware as 1.0V PMP9738 but demonstrates operation at 600mV output up to 200 A off 12V input. Fixed on time mode and reduced switching frequency at 600mV help reduce losses and improve thermal balance between FETs.
Testing at 120A output with 3 & 4 phases and lower cost Power Stage also included. Design 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.
