Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX20057ATIE/VY is a highly integrated automotive triple output PMIC consisting of two synchronous buck converters and an asynchronous boost controller available in 2.1MHz and 400kHz frequencies. The boost controller can be used to supply power to the buck converters and maintain voltage regulation during cold-start operation with a battery input as low as 2V. The two high-voltage synchronous buck converters operate 180° out of phase. The integrated circuit operates at input voltages from 3.5V to 36V and can operate at 95% duty cycle in dropout conditions. It is suitable for medium- to high-power applications that require operation over a wide input voltage range, such as automotive cold start or engine stop-start conditions.

• 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?
