DC2057A - LTC3638 Demo Board | 4V ≤ VIN ≤ 140V, Vout = 1.8V/3.3V/5V/Adj @ 250mA

Demonstration circuit 2057A is a high input voltage, 250mA output DC/DC power supply featuring the LTC®3638. The IC operates with high efficiency Burst Mode® operation and includes an internal high side power MOSFET. The board will accept an input voltage between 4V and 140V, and provide jumper selected output voltages of 1.8V, 3.3V, 5V with an option for additional voltages. The IC includes internal soft-start and a provision for increasing soft-start time.
