The MAX761 evaluation kit (EV kit) provides a 12V out-

put for programming flash memories and powering

other circuitry. From 5V inputs, it provides better than

85% efficiency for 4mA to 200mA loads. Quiescent

supply current is only 300µA from a 5V input, and drops

to 1µA in logic-controlled shutdown. The MAX761

comes in an 8-pin SO package and uses tiny external

components; the entire circuit fits into less than 0.3in

19-0241; Rev 1; 8/07
