UC3655 General Description

The UTC UC3655 is a synchronous-rectification type DC/DC converters with a built-in 0.6Ω P-channel driver transistor and 0.7Ω N-channel switching transistor, which designed to allow the use of ceramic capacitors. Using only a coil and two capacitors connected externally, the UC3655 enable a high ef.
