DC1559A - LTM8046 Demo Board | 2kVAC Isolated Flyback µModule Converter, 3.2V ≤ VIN ≤ 26V, Vout = 5V @ Up to 550mA

The demo circuit 1559A features the LTM8046, a 2kVAC, 2.5W isolated flyback μModule® converter. The demo circuit is designed for a 5V output from a 3.2V to 26V input. The typical current capability of the 5V output varies with input voltage from about 150mA at V_IN = 4V to about 550mA at V_IN = 26V. R2 provides the necessary minimum load current to keep the V_OUT in regulation throughout the entire input voltage range. Please see the Typical Performance Characteristics curves in the LTM8046 data sheet to determine the minimum load current for other input/ output configurations.
