AW9962HDNR数据手册Awinic中文资料规格书

描述 Description

The AW9962H is a white LED (WLED) driver with integrated boost converter. The boost converter runs at 1.1MHz fixed switching frequency, with an internal 40V, 2A switch FET, the AW9962H can drive one string (up to 10 LEDs) and parallel LED strings. The full-scale WLED current can be set by the equation 200mV/RSET. RSET should be changed for parallel applications.The current of WLED can also be set with duty cycle of PWM signal applied to the CTRL pin with 10kHz~100kHz.AW9962H integrates built-in soft-start function to minimize the power supply inrush current. AW9962H also integrates over-current protection, LED open protection and over temperature protection (OTP) to prevent chip from entering abnormal operating conditions.
