The MP6003 is a monolithic flyback DC-DC converter which includes a 150V power switch and is capable of delivering up to 15W output power. It can also be used for SEPIC boost and Flyback and Forward applications. The MP6003 uses the fixed-frequency peak current mode primary controller architecture. It has an internal soft-start, auto-retry, and incorporates over current, short circuit, and over voltage protection. The MP6003 can also skip cycles to maintain zero load regulation. It has a direct optocoupler interface which bypasses the internal error amplifier when an isolated output is desired. The MP6003 is ideal for telecom applications, and is available in a compact, thermally enhanced SOIC8 package with an exposed pad.
