DC2275A

Demonstration circuit DC2275A features the LT®8331 in boost configuration. The demo circuit demonstrates small size and low component count. The boost is designed to convert a 10V to 48V source to 120V at 25mA to 80mA. DC2275A includes an optional circuit on the back of the board for a charge pump that can be used to double the output voltage. The LT8331 can operate with inputs as high as 100V but in this demo circuit, the input is limited by the voltage rating of the input capacitor. The LT8331 includes many other features such as synchronization to external clock, user configurable undervoltage lockout, soft-start, frequency foldback and it is easily configured as boost, SEPIC or inverting converter.
