Test Procedure for MC34063 Inverting Regulator (Leaded) 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 Inverting 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 P602. Attach 5 VDC source to connector P601 – observe polarity. Turn on 5 VDC source. Measure DC output voltage at connector P602. DC voltage should be -12.35V +/- 0.3V. Remove load. Measure DC output voltage at connector P602. DC voltage should be -12.35V +/- 0.3V. Remove 5 VDC source and disconnect load – test complete.
