Description
The PMP10961 is a high power density, 10A buck converter with PMBus interface. The layout is optimized for small form factor utilizing both sides of board and fits in a 0.6"x0.78" area. It enables 86.5% efficiency at 10Vin, 1.2V/10Aout, 400kHz. Due to DCAP3 control mode, it also provides fast load transient response within +/-1.5%, minimizing output capacitors . PMBus interface enables output voltage adjustment, soft-start, power-on delay, switching frequency, UVLO and fault reporting.
Features
