Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MP4571GQB is a fully integrated fixed frequency synchronous buck converter. It achieves up to 1A continuous output current and features peak current control for excellent transient response. The wide input voltage range of 4.5V to 60V is suitable for a variety of step-down applications in automotive input environments, and the 2μA off-mode quiescent current makes it ideal for battery-powered applications.

The MP4571GQB integrates internal high-side and low-side power MOSFETs for high efficiency without the need for external Schottky diodes, and is available in a 12-pin QFN package.

• 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?
