AW9963CSR

White LED Driver with PWM Brightness control in Small Package

The AW9963 is dual-channel WLED driver which provides highly integrated solutions for single-cell Li-ion battery powered smartphone backlight. The AW9963 built-in a 2A/40V power MOSFET which can drive up to 2p10s WLED diodes with Li- ion battery power supply. It also integrates two high accuracy and matching current sink regulators which can significantly improve uniformity of backlight, very low feedback voltage and PFM mode at light load bring AW9963 higher efficiency. The AW9963 supports 10kHz to 100kHz PWM input range, can provide low to 0.1% stable current. The AW9963 integrates built-in soft start, as well as overvoltage, overcurrent, and thermal shutdown protections.
