[sense(+) ? sense(-)] ? 5% of v o,nom . the voltage between the vo(+) and vo(-) terminals must not exceed the minimum output overvoltage shut-down value indicated in the feature specifications table. this limit includes any increase in voltage due to remote-sense compensation and output voltage set-point adjus tment (trim). see figure 17. if not using the remote-sense feature to regulate the output at the point of load, then connect sense(+) to vo(+) and sense(-) to vo(-) at the module. although the output volta ge can be increased by both the remote sense and by the trim, the maximum increase for the output voltag e is not the sum of both. the maximum increase is the larger of either the remote sense or the trim. the amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. when using remote sense and trim: the output voltage of the module can be increased, which at the same output current would increase the power output of the module. care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power. figure 17. effective circuit configuration for single-module remote-sense operation output voltage. output voltage set-poi nt adjustment (trim) trimming allows the user to increase or decrease the output voltage set point of a module. this is accomplished by connecting an external resistor between the trim pin and either the sense(+) or sense(-) pins. the trim resistor should be positioned close to the module. if not using the trim feature, leave the trim pin open. with an external resistor between the trim and sense(-) pins (radj-down), the output voltage set point (vo,adj) decreases (see figure 18). the following equation determines the required external- resistor value to obtain a percentage output voltage change of %. for output voltages: 28v ? ? ? ? ? ? ? = ? k r down adj 2 % 100 where, 100 % , , ? = nom o desired nom o v v v v desired = desired output voltage set point (v). with an external resistor connected between the trim and sense(+) pins (radj-up), the output voltage set point (vo,adj) increases (see figure 19). the following equation determines the required external-resistor value to obtain a percentage output voltage change of %. for output voltages: 28v ( ) ? ? ? ? ? ? + ? + = ? k v r nom o up adj % %) 2 100 ( % * 225 . 1 % 100 * , where, 100 % , , ? = nom o nom o desired v v v v desired = desired output voltage set point (v). the voltage between the vo(+) and vo(-) terminals must not exceed the minimum output overvoltage shut-down value indicated in the feature specifications table. this limit includes any increase in voltage due to remote-sense compensation and output voltage set-point adjus tment (trim). see figure 17. although the output volta ge can be increased by both the remote sense and by the trim, the maximum increase for the output voltag e is not the sum of both. the maximum increase is the larger of either the remote sense or the trim. the amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. when using remote sense and trim, the output voltage of the module can be increased, which at the same output current would increase the power output of the module. care should be taken to ensure that the maximum output power of
