_______________General Desc ription
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
