INITIAL RELEASE – SPECIFICATIONS SUBJECT TO CHANGE
DESCRIPTION
The MP6001 is a monolithic Flyback/Forward
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 boost and
SEPIC applications.
The MP6001 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 MP6001 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 MP6001 is ideal for telecom applications,
and is available in a compact, thermally
enhanced SO8 package with an exposed pad.
