Output Trim Equations
Equations for calculating the trim resistor are shown below. The Trim Down resistor should be connected
between the Trim pin and Sense (-) pin. The Trim Up resistor should be connected between the Trim pin and the
Sense (+). Only one of the resistors should be used for any given application.
Minimum trim down voltage is 10.8V
Maximum trim up voltage is 13.2V.
The total voltage increased by trim and remote sense should not exceed 10% of the nominal output voltage.

Remote Sense
This module has remote sense compensation feature. It can minimize the effects of resistance between
module’s output and load in system layout and facilitates accurate voltage regulation at load terminals or
other selected point.
1. The remote sense lines carries very little current and hence do not require a large cross-sectional area.
2. This module compensates for a maximum drop of 10% of the nominal output voltage.
3. If the unit is already trimmed up, the available remote sense compensation range should be
correspondingly reduced. The total voltage increased by trim and remote sense should not exceed 10%
of the nominal output voltage.
4. When using remote sense compensation, all the resistance, parasitic inductance and capacitance of the
system are incorporated within the feedback loop of this module. It can make an effect on the module's
compensation, affecting the stability and dynamic response. A 0.1uF ceramic capacitor can be
connected at the point of load to de-couple noise on the sense wires.
5. Recommend the connection of remote sense compensation as below figure. There are a resistor RS+
(100 ohm) from Vo+ to Sense+ and a resistor RS- (51 ohm)) from Vo- to Sense- inside of this module.

6. If not using remote sense compensation, please connect sense directly to output at module's pin, that is,
connect sense+ to Vo+ and sense- to Vo- at module's pin, the shorter the better. See below figure.

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 0.5A during
hiccup.
Vin=48V
Expansion of on time portion
Over Voltage Protection
The output over voltage protection consists of circuitry that monitors the voltage on the output terminals. If the
voltage on the output terminals exceeds the over voltage protection threshold, the module will shutdown into
hiccup mode and restart once every 800mS. The module operates normally when the fault is cleared.

Over Temperature Protection
The OTP is achieved by thermistor RT1 and the threshold is set at 120C in non-latch mode; the hottest
component Q13 reaches 130C with 100LFM air flow correspondingly. It will restart automatically when the
temperature falls down to 110C. The protecting point will be varied a little under different conditions (air flow,
ambient temperature, input voltage, load...).
