AW9962E
Every spec below is cited to the manufacturer datasheet. Pick your exact ordering code, compare the closest alternatives, then ask the assistant what it means for your design.
What the AW9962E family does
The AW9962E is a high-efficiency boost WLED driver with an integrated 40V, 2A switch FET operating at a fixed 1.1MHz switching frequency. It supports 0.3% PWM dimming, accepts a 2.7V to 5.5V input voltage, and drives up to ten series-connected LEDs with 38V over-voltage protection. The device features built-in soft-start, over-current, and over-temperature protection to ensure safe operation. Engineers typically use this component in mobile phones, portable media players, PDAs, and GPS receivers to power white LED strings efficiently.
