DESCRIPTION

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.
