Test Procedure for the NCP59744MN2ADJGEVB Evaluation Board V V A REGULATED DC SUPPLY VBIAS A ELECTRONIC LOAD REGULATED DC SUPPLY VIN VOUT V V A VPG Figure 1: Test Setup Test Procedure 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. Connect the test setup as shown in Figure 1. Apply supply voltage Vin = 1.5 V Apply supply voltage Vbias = 5.0 V Apply Iout = 10 mA load. Check that Vout is 1.2 V Increase Iout load current to 3.0 A Check that Vout is 1.2 V Decrease Iout load current to 10 mA Check that voltage on PG output VPG is 5 V Decrease Vin voltage to 0.9 V Check that voltage on PG output VPG < 0.1 V Power down the load Power down Vin and Vbias supply End of test 7/22/2014 1 www.onsemi.com
