In order to improve efficiency and maximize battery life, the driving current of the LED is pulse current, and the rectifier circuit is removed. The so-called pulse current is because there is no output capacitor, and the LED only has driving current when the switch tube is turned off, and does not work when the switch tube is turned on. Since the inductor current is completely used to drive the LED, the peak current of the inductor is relatively small at this time. High battery life LED circuit based on GEC8310:
