AL62 6 Pin Light Control IC

The AL62 6 Pin Light Control IC handles one job on a mobile phone board: it drives the LED string that lights up the display. Marked "AL62" on the package and built around the AW9962DNR die from Shanghai Awinic Technology, this chip sits in the backlight power circuit between the battery rail and the LED string running along the display panel. When a phone comes into your workshop with a screen that shows the display but shows no light, or a backlight that flickers, dims randomly, or cuts out after a drop, this IC is one of the first components you check.You'll find the AL62 on board designs used across several Huawei, Oppo, and Vivo models, including the Huawei Enjoy 8E series, Oppo A5 and A71, and Vivo Y93 and the 8e/4e/7a series. Manufacturers reuse this driver footprint across multiple board revisions because it's a proven, compact solution for controlling backlight brightness, so you'll come across the same AL62 marking on boards you wouldn't necessarily expect from the model number alone. Before you order, pull the old IC or check the marking under your microscope and confirm it reads AL62, since AL61 and AL65 sit on similar footprints but carry different internal specs.Functionally, the AL62 is a PWM white LED driver. It takes a PWM signal on its control pin and converts the duty cycle into a regulated feedback voltage, which sets how much current flows through the LED string. That's what gives you smooth, flicker-free brightness control instead of a fixed on/off backlight. The chip also supports CABC operation, meaning it can respond to content-adaptive brightness commands from the display controller, adjusting backlight intensity based on what's on screen to save power. Switching frequency runs at 1.1MHz, which keeps the LED drive stable and reduces audible coil whine compared to slower switching designs. On the protection side, the AL62 carries 38V over-voltage protection and can safely drive up to 10 LEDs in series, covering the LED string lengths used in most smartphone backlight circuits.In the repair workflow, backlight IC replacement sits in the power and display diagnostics stage, right after you've ruled out a bad LCD panel, a broken backlight fuse or resistor, or a damaged flex cable. If your board powers on, boot loop isn't present, and the display shows content under a flashlight but nothing at normal brightness, the fault usually traces back to the backlight driver circuit rather than the panel itself. Reballing or hot-air removing the old AL62, cleaning the pads, and reflowing a genuine replacement restores backlight function without needing a full board swap or a new display, which keeps the repair cost down for your customer.This listing is for a genuine AL62 (AW9962DNR), 6-pin TDFN2x2-6L package, tested and checked before shipping. It's built for technicians running board-level repairs on Huawei, Oppo, and Vivo devices where backlight failure is a recurring fault. Handle it with proper ESD precautions and confirm your hot air station's temperature profile matches the TDFN package before reflowing, since overheating a small 6-pin part like this can damage the die before it ever sees a board. Pair it with a fine-tip soldering iron or hot air nozzle sized for small ICs, flux, and a stencil or manual paste application for consistent results on your repair bench.Stock this IC alongside your other backlight and power management components for Huawei, Oppo, and Vivo boards, and keep your bench ready for the next dead-backlight job that walks through the door.
