The PMP21278 reference design is a 300W power supply utilizing the LM5176 4-switch buck-boost controller for industrial applications. This design can operate from 9V to 50V. The design has a 12V output and capable of sourcing 25A continuous current. Switching frequency is set to 230kHz. PMP21278 is assembled on SV601348A PCB. Three 6.8mF, 65V rated electrolytic capacitors are used to damp the input supply’s wiring inductance for all test data taken on this test report.
