Driving circuit that controls LED brightness using PWM signal
Source: InternetPublisher:张七岁 Keywords: PWM LED drive circuit Updated: 2024/08/28
In the circuit below, the EN terminal of the IC is the terminal that enables the switching converter to operate in ON/OFF mode. If a PWM signal is applied to the EN terminal, the white light LED will operate in ON/OFF mode at a certain speed, thereby achieving control of the LED brightness.
