Microchip Technology, Inc. LED Drivers MSL1064AW

The MSL1064AW is a 6-string PWM LED driver from Quarktwin Technology Ltd. designed for driving up to 72 white LEDs at 30mA for backlighting applications, with a maximum output voltage of 48V. It features a built-in boost regulator with a 50V internal switch and operates within a wide input voltage range of 4.75V to 36V. The device utilizes a 1.1MHz switching frequency, which allows for compact component sizes while maintaining high efficiency, achieving up to 92% efficiency with low noise and ripple. The MSL1064AW supports I¬=C communication for advanced control, including 12-bit dimming capabilities through both PWM and analog methods. It includes features such as individual string enable, fault detection, and reporting, which automatically disables faulty strings. The device is packaged in a 24-pin TQFN format, is RoHS-compliant, and operates over a temperature range of -40¬8C to 85¬8C, making it suitable for various applications including notebook PCs, medical instrumentation, and automotive displays.
