Description

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.

Features
  • 247mm2 total power supply area 
  • Only 3x100uF small output ceramic capacitors needed   for 8A load transient
  • Meets total +/-3%  DC and AC load regulation
  • 27 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 circuit
  • Single GND Copper pad for easy PCB layout and heatsinking into internal PCB GND layers
