S&M2460 Research Paper of Special Issue https://doi.org/10.18494/SAM.2021.3020 Published: January 31, 2021 High-speed and High-current Phase Width Modulator Driver for High-power Infrared LEDs [PDF] Jye-Chau Su and Cheng-Tao Tsai (Received June 21, 2020; Accepted October 13, 2020) Keywords: pulse width modulation (PWM), light-emitting diodes (LEDs)
In this paper, a high-speed and high-current pulse width modulation (PWM) driver for high-power infrared light-emitting diodes (LEDs) is proposed. High-power infrared LEDs have been widely used in applications of distance measurements, in which the LEDs must be driven by a pulse-current driver. The pulse-current driver must have a high pulse current (about 1 A or more) and achieve high-speed PWM (a pulse width of about 200 ns or less). Because the traditional PWM drivers cannot meet the requirements for testing the performance of high-power and high-speed infrared LEDs, a prototype high-speed and high-current PWM driver is built to overcome this problem. Experimental results verify the performance and the feasibility of the proposed PWM driver for high-power infrared LEDs.
