Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LMQ644A2QRXARQ is a 36V synchronous DC/DC buck controller providing high current single or dual outputs. The device features an interleaved, stackable current mode control architecture for easy loop compensation, fast transient response, excellent load and linear tuning rates, and accurate current sharing, with one output clock that can be stacked up to 6 phases with currents up to 36 A. The 50ns minimum on-time of the high-side switches enables a high step-down ratio, converting 12V, 24V, or automotive inputs directly to low voltage rails, thus reducing system complexity and design cost. This reduces system complexity and design 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?
