The LT8335 is a current mode DC/DC converter capable of generating either positive or negative output voltages using a single feedback pin. It can be configured as a boost, SEPIC or inverting converter consuming as low as 6μA of quiescent current. Low ripple Burst Mode operation maintains high efficiency down to very low output currents while keeping the output ripple below 15mV in a typical application. The internally compensated current mode architecture results in stable operation over a wide range of input and output voltages. Integrated soft-start and frequency foldback functions are included to control inductor current during start-up. The 2MHz operation combined with the small 8-lead DFN package, enables low cost, area efficient solutions.

Product Detail

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.
