DESCRIPTION

The MP6002 is a monolithic Flyback/Forward

DC-DC converter which includes a 150V power

switch and is capable of delivering up to 30W

output power. It can also be used for boost and

SEPIC applications.

The MP6002 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 MP6002 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 MP6002 is ideal for telecom applications,

and is available in a compact, thermally

enhanced SO8 package with an exposed pad.
