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 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
