Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The IW3631-00 two-stage LED driver is a dimmable digital offline PWM controller for solid-state lighting applications up to 120W with high power factor (PF >0.95) and low THD (<10%). It features a built-in driver for isolation transformers that enables direct, 0-10V dimming without the need for an external MCU and driver circuit, reducing cost and complexity. The iW3631 can also be implemented to support a PWM dimming interface to simplify use in wireless SSL applications.

The IW3631-00 operates in a quasi-resonant mode to provide high efficiency and uses Renesas' PrimAccurate™ advanced primary-side sensing technology to achieve excellent line and load regulation without secondary feedback components. The digital control algorithms used by the iW3631 maintain stability over all operating conditions without the need for any external loop compensation components, minimizing the BOM cost.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?
