High Density 900mV 220 A 6 Phase DC-DC Buck Converter with PMBus Interface Reference Design
PMP11208 PMP11208 has same hardware as 1.0V PMP9738 and 0.6V PMP10393 but demonstrates operation at 900mV output up to 240 A off 11V, 12V and 13V inputs. While the design is in quasi fixed frequency mode for 1.0Vout and in fixed on time mode for 600mVout, it can be in either mode at 900mVout depending upon (...)
