Output voltage programmable from 0.6V to 3.3V, 0.9V to 6.0V, 3.0V to 6.0V, and.0v to V by connecting a single resistor between the TRIM and GND pins of the module. To calculate the value of the resistor (R trim ) for a particular output voltage (Vo), use the equations shown in Table. 7. CV2S : When Vo, set < 0.9VDC the input voltage range is VDC. 8. CV24S-3000 and CV24S2-3000: An external π filter on the input of the module is recommended to minimize input reflected ripple. The filter is shown in Figure The ON/OFF control pin voltage is referenced to GND. 0. Both vertical mounting and horizontal mounting SIP types are available. Add the suffix A to the model number for horizontal mounting SIP type.. CAUTION: This power module is not internally fused. An input line fuse must always be used.
