PMP15007 uses the LM5161-Q1 in a Fly-Buck topology with the primary and secondary output both set to 5V nominal. The circuit accommodates a voltage input range from 36V to 72V, ideal for the 48V nominal input rail. While the primary side is set at 5.32V nominally, the secondary isolated side sees 5V when using feedback resistors and is based on Coilcraft’s LPD8035V series coupled inductor set at a turns-ratio of 1:1. The maximum operating current on both the primary and secondary rails are set at 225 mA each. The switching frequency is set at 315 kHz nominal.
