DC1560A: Isolated 5V @ 300mA, 4.5 ~ 30V in

Summary

Demo circuit 1560A is an isolated flyback μModule DC/DC converter with LDO post regulator featuring LTM8048.

The demo circuit is designed for a 6V flyback output and a 5V post regulator output from a 4.5V to 30V input. The typical current capability of the 6V flyback output varies with input voltage from about 110 mA at VIN = 4.5V to about 370 mA at VIN = 30V.
