Additional configuration available. Consult factory for details. Voltage Regulation Less than 1% (no load to full load, –40 C to +85 C) For voltage output below 5V, Less than 3% (no load to full load, –40 C to +85 C) Remote Sense AUX SENSE The AUX SENSE line is used to achieve accurate voltage regulation at load terminals. To use this feature, connect this pin directly to load's positive terminal. If this function is not required, short AUX SENSE pin to AUX OUTPUT pins as close as possible to the unit. AUX SENSE RTN The AUX SENSE RTN line is used to achieve accurate voltage regulation at load terminals. To use this feature, connect this pin directly to load's negative terminal. If this function is not required, short SENSE RTN pin to OUTPUT RTN pins as close as possible to the unit. Note: The use of remote sense has a limit of voltage dropout between the converter's output and the load's terminals of approximately ±0.5V of nominal output voltage. Turn on Overshoot Output voltage overshoot during power on < 5% Ripple and noise For Vout>5V typical max 1% For Vout< 5V typical max 2% With 1μF external capacitance.
