PMP21274 is a single-phase boost utilizing the LM5122 controller. This reference design can operate from 12V to 50V. The design has an output of 54V and capable of sourcing 2.5A continuous current. LM5112 has a bypass function where Vin is equal or greater than the set output voltage, the device will bypass Vin via the high side sync FET. Switching frequency is set to 230kHz, and a 4 layer PCB is used.
