Shiftas:Try a small low-ESR capacitor on the YX8122 power supply pins, perhaps try 10uH or 100uH. Also try two white LED's in series, or using a 1.5v cell. The boost output voltage might not be high enough over the input voltage, and the straight-through path might be preventing oscillation. My rule of thumb is that a boost circuit should at least double the voltage. | |
