DC2357A - LTM8067 Demo Board | 2kV AC Isolated Flyback μModule, 4.5V ≤ VIN ≤ 40V, Vout = 5V @ up to 500mA

The Demo circuit 2357A is a 2kV AC isolated flyback μModule® DC/DC converter featuring the LTM8067. The demo circuit is designed for a 5V flyback output from a 4.5V to 40V input. The typical current capability of the 5V flyback output varies with input voltage from about 200mA at 4.5VIN to about 500mA at 40VIN. See Figure 1 in the demo manual for the maximum load current as a function of VIN. Output resistor R1 provides the necessary minimum load current to keep the output voltage in regulation throughout the entire input voltage range. Please see the typical performance characteristic curves in the LTM8067 data sheet to determine the minimum load current for other input/output configurations.
