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  
Minimum trim down voltage is 12V  
Maximum trim up voltage is 16.5V.  
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 incorpotated within the feedback loop of this module. The 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+  
(51.1 ohm) from Vo+ to Sense+ and a resistor RS- (51.1 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 overcurrent condition persists beyond a few  
milliseconds, the module will shut down into hiccup mode and restart once every 500mS. The module operates  
normally when the output current goes into specified range. The typical average output current is 215mA during  
hiccup.  
Expansion of on time portion of above figure  
Vin=48V  
CH4: Output current waveform  
Over Voltage Protection  
The output overvoltage 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.

Thermal Derating Curve  
The OTP is achieved by thermistor R12 and the threshold is set at 125C in non-latch mode; the hottest  
component Q1 reaches 125C with 100LFM air flow correspondingly. It will restart automatically when the  
temperature falls down to 100C. The protecting point will be varied a little under different conditions (air flow,  
ambient temperature,input voltage, load...).  
Maximum junction temperature of semiconductors derated to 120 degree C.
