PMP7882 is a single-phase switching regulator accepting an input voltage range of 10.8Vin to 13.2Vin and providing an output voltage of 1.2Vout capable of supplying 12A of current. This design uses the LM27402 synchronous buck controller with lossless inductor DCR current sensing capability, which eliminates the need to add resistive powertrain elements and increases overall efficiency.
