Product Details

Demonstration circuit 1882 is a high voltage inverting charge pump featuring the LTC3261EMSE. The LTC3261 operates with an input voltage from 4.5V to 32V and provides up to 100mA of output current. The output voltage is unregulated and is the negative of the input voltage (-VIN). The demo board provides selectable Burst Mode^® operation or constant-frequency mode operation, plus allows selection of the operating frequency (500kHz, 200kHz or 50kHz).
