描述 Description

The AW9962E 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 AW9962E 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.AW9962E integrates built-in soft-start function to minimize the power supply inrush current. AW9962E also integrates over-current protection, LED open protection and over temperature protection(OTP) to prevent chip from entering abnormal operating conditions.
