Test Procedure for the NCP1597A Evaluation Board Figure 1: Test Setup The following steps describe the test procedure for all of these boards: Suggested 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 6 A DC (e.g. FLUKE 89 IV)……………… 1pc DC Electronic Load (e.g. AGILENT 6060B) ……………………………………... 1pc 05/13/10 -1- www.onsemi.com Test Procedure: 1. Connect the test setup as shown in Figure 1. 2. Apply an input voltage, VIN = 4-5 Vdc (Current Limit must be set to 4A) 5. Apply IOUT(load) = 0 A 4. Check that VOUT = 1.7 – 1.9 Vdc 6. Set IOUT to desired level 0 A- 2 A 7. Check that VOUT = 1.7 – 1.9 Vdc 8. Turn off the load 9. Turn off VIN 10. End of the test 05/13/10 -2- www.onsemi.com
