Connect the test setup as shown in Figure 1.* 2. Apply an input voltage, VIN = 4-5 Vdc (Current Limit must be set to 5A) 5. Apply IOUT(load) = 0 A 4. Check that VOUT = 1.1 – 1.9 Vdc 6. Set IOUT to desired level 0 A- 3 A 7. Check that VOUT = 1.15 – 1.25 Vdc 8. Turn off the load 9. Turn off VIN 10. End of the test *Keep lead length from Input Supply to IN,GND connections short. 7/25/2012 -2- www.onsemi.com
