DC1923A - LTC3129-1 Demo Board | 2.42V to 15V Input, 5V out at 200mA

Demonstration circuit 1923A features the LTC3129-1, a high efficiency 200mA output buck-boost DC/DC converter with a wide VIN and VOUT range. The DC1923A operates with a 2.42V to 15V input voltage range, and has been designed with the output voltage set to 5V. The demo board can be programmed to any of eight voltage settings (2.5V, 3.3V, 4.1V, 5V, 6.9V, 8.2V, 12V, 15V) by using jumpers.
