Nov. 17, 2010 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.

Nov. 17, 2010 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. 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+ (100 ohm) from Vo+ to Sense+ and a resistor RS- (51 ohm)) from Vo- to Sense- inside of this module. RS+ Vo+ Sense+ Load RS- Sense- V o- 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.
