Description
The 0RQB-Q8S12x is an isolated dc/dc converter that operates from a nominal 50 Vdc source. This converter is
intended to provide isolation and step down to generate a regulated intermediate bus for the purpose of powering
non-isolated Point-of-Load (POL) converters. This unit will provide up to 480 W of output power from a nominal
50 Vdc input.

Over Current Protection
To provide protection in a fault output overload condition, the module is equipped with internal current-limiting
circuitry and can endure current limiting for a few mili-seconds. If the over current condition persists beyond a few
milliseconds, the module will shut down into hiccup mode and restart once every 400mS. The module operates
normally when the output current goes into specified range. The typical average output current is 3.8A during
hiccup.

Thermal Derating Curve
Maximum junction temperature of semiconductors derated to 120 degree C.
AIR FLOW
Bottom view
The OTP is achieved by temperature sensor U10 and it is in non-latch mode when the hottest component Q9
reaches 125C with 200LFM air flow correspondingly. It will restart automatically when the temperature falls down
to 105C. The protecting point will be varied a little under different conditions (air flow, ambient temperature, input
voltage, load...).
