12Vin to 67Vin: 54Vout at 4.8A: 260W Dual-Phase Boost Reference Design
PMP7979 is a synchronous dual-phase boost power supply using the LM5122 controllers. The design accepts an input voltage of 12 V to 67 V: and boosts a 54-V output rail that is capable of sourcing 4.8-A continuous current. The LM5122 has an internal current source to keep the high-side FET to run at 100% duty cycle: which allows a bypass operation when the input voltage is greater than the configured output voltage.
