SOT23-6L

PWM control input for CABC operation 1.1MHz Switching Frequency 38V Over-voltage Protection for up to 10 LEDs ｉｎ Series 200mV Reference Voltage 2.7V to 5.5V Input Voltage Range Over-current ａｎｄ Over-temperature Protection Built-ｉｎ Soft-start Limits Inrush Current SOT23-6L package

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.
