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 load and actual Vin. Testing focused upon detailed static and dynamic loading in and between both modes to show a seamless transition between the two modes.
Features
- Same hardware as 1.0Vout PMP9738, but with 900mV output testing up to 240A
- DCAP+ control for excellent step load response, SVID and PMBus interfaces
- Thermal performance & dynamic response verified at 900mV output off 11V, 12V & 13V
- Focus of evaluation board is on ease of electrical testing with almost all parts on top side
• Rich test interface including PMBus socket, 5V & 3.3V biases and onboard high speed dynamic test load
