Test Procedure for MC34063 Boost Regulator (SMD) Demonstration Board h 11/11/2003 Three Black Test Leads 12 VDC Power Supply Four Alligator Clips Table 1: Required Equipment Three Red Test Leads 100mA load (or 33 ohm, 1W resistor) MC34063 Boost Regulator Digital Multimeter Figure 1: Test Procedure for MC34063 1. 2. 3. 4. 5. 6. 7. 8. 9. Attach 50 mA load (or 240 ohm, 1 W resistor) to connector P402. Attach 3.3 VDC source to connector P401 – observe polarity. Turn on 3.3 VDC source. Measure DC output voltage at connector P402. DC voltage should be 12.0V +/- 0.3V. Remove load. Measure DC output voltage at connector P202. DC voltage should be 12.0V +/- 0.3V. Remove 3.3 VDC source and disconnect load – test complete.
