Product Details

Demonstration circuits 2449A-A and 2449A-B feature the LT8335, in boost and inverting configurations. The demo circuits demonstrate small size and low component count. The boost is designed to convert a 3V to 10V input source to 12V at 275mA. The inverter converts a 4.5V to 13V source to –12V at 350mA. Refer to Figures 4 and 5 in the manual for maximum load current at different input voltage levels.
