MGDK04 4W POWER
WIDE INPUT RANGE ISOLATED DC/DC CONVERTER
0.3’’ LOW PROFILE
Description
The MGDK04 series features a Quality Cost Effective range of 4W board mounted isolated dc/dc
converters. With multiple selection of wide input voltage ranges, the MGDK04 is proposed with a single
symmetrical or triple output channel. The converter embeds an output short circuit protection, and
comes encapsulated in a low profile fully potted DIL 24 compliant metallic case.

ON-OFF FUNCTION
The converter is naturally enabled as far as the on/off
pin remains unconnected. To disable the converter the
pin on/off should be shorted to Go using a switch, an
open collector or open drain transistor. Several
converters of the same input bus can be remotely
controlled by the same signal just by connecting all the
pins on/off together.

OCP FUNCTION
The converter series incorporates an over current
protection circuit. When the output current reaches a
value above typically 200% of it’s full-rated current, the
converter falls into hiccup mode by testing periodically if
an overload is applied. The module restarts automatically
to normal operation when overcurrent is removed.
