PMP9146 Reference Design

Texas Instruments

Communication ASIC Core Power Supply Reference Design


The PMP9146 utilizes the TPS53515 DCAP3-mode SWIFT stepdown DC-DC converter to power high-current ASIC core rails at 1.2Vout/12A: with only 247mm2 of total power supply area and 27 total components.

  • 247mm2 total power supply area Only 3x100uF small output ceramic capacitors needed   for 8A load transientMeets total +/-3%  DC and AC load regulation27 total power supply components (including IC)DCAP3 control mode requires no loop compensation:  and can use ceramic output caps with no need for external ripple synthesizer circuitSingle GND Copper pad for easy PCB layout and heatsinking into internal PCB GND layers
