Test Procedure for the NCP1034BCK5VG Evaluation Board Figure 1: Test Setup The following steps describe the test procedure for all these boards: Required Equipment: Current limited DC Power Supply (e.g. AGILENT 6645A) ……………………… 1pc DC Volt-Meter able to measure up to 60 V DC (e.g. KEITHLEY 2000) ………… 2pcs DC Amp-Meter able to measure up to 1 A DC (e.g. KEITHLEY 2000) ………......1pc DC Amp-Meter able to measure up to 5 A DC (e.g. FLUKE 89 IV)……………… 1pc DC Electronic Load (e.g. AGILENT 6060B) ……………………………………... 1pc Test Procedure: 1. Connect the test setup as shown in Figure 1. 2. Apply an input voltage, VIN = 48 Vdc 3. Apply IOUT(load) = 0 A 4. Check that VOUT = 5 Vdc 5. Set IOUT to 5 A 6. Check that VOUT = 5 Vdc 7. Turn off the load 8. Turn off VIN 9. End of the test 6/24/2008 -1- www.onsemi.com
