LTC3638 Demo Board DC2057A

Analog Devices LTC3638 Demo Board DC2057A is an evaluation board featuring a high input voltage, 250mA output, DC-DC power supply example circuit based on the LTC3638 Step-Down Regulator. The LTC3638 operates with high-efficiency Burst Mode® operation and includes an internal high-side power MOSFET. The LTC3638 Demo Board DC2057A will accept an input voltage between 4V and 140V and provide jumper-selected output voltages of 1.8V, 3.3V, and 5V with an option for additional voltages. The LTC3638 IC includes an internal soft-start and a provision for increasing soft-start time.
