Product Details

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 110mA at VIN = 4.5V to about 370mA at VIN = 30V. The circuit provides 725VDC isolation.
