Test Procedure for the NCV898031SEPGEVB Evaluation Board 1. Connect a DC input voltage, within the 6 V to 40 V range, between VIN and GND. 2. Connect a DC enable voltage, within the 2.0 V to 5.0 V range, between EN/SYNC and GND. 3. The demo board feedback components were selected for continuous operation at rated 7 V/1.22 A output power at a minimum input voltage of 6 V. The NCV898031 VIN has its operational voltage diode-ORed between the converter output (12 V) and input voltages. The converter turns-on typically at 6.7 V. Once energized, the output voltage supplies power to the IC when the battery voltage is below (approximately) 11.5 V. The decreasing VIN UVLO voltage depends on load current as well as VIN, and will be less than 6 V when operating below rated output current. 1/30/2013 www.BDTIC.com/ON/ -1- www.onsemi.com
