DC2358A - LTM8068 Demo Board | 2kV AC Isolated μModule Flyback with LDO, 4.5V ≤ VIN ≤ 40V, Vout1 = 5.6V @ up to 460mA, Vout2 = 5V Post-Reg LDO

The Demo Circuit 2358A is a 2kV AC isolated flyback μModule® DC/DC converter with LDO post regulator featuring the LTM8068. The demo circuit is designed for a 5.6V flyback output and a 5V post regulator output from a 4.5V to 40V input. The current capability of the 5.6V flyback output (VOUT1) varies with input voltage from about 200mA at 4.5VIN to about 460mA at 40VIN. The current capability of the 5V LDO output (VOUT2) is limited by either the  VOUT1 loading or the 300mA current limit on the LDO post regulator itself. Figure 1 in the demo manual shows the maximum output current on VOUT1 when VOUT2 is not loaded, and VOUT2 when VOUT1 is unloaded.
