Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX17631AATE is a high efficiency, high voltage, synchronous step-down DC-DC converter with an integrated MOSFET that operates over a 4.5V to 36V input voltage range. The devices can deliver up to 1.5A of current.

The MAX17631AATE utilizes a peak current mode control architecture. The device can operate in three switching states, forced pulse width modulation (PWM), pulse frequency modulation (PFM) or discontinuous conduction mode (DCM), which supports high efficiency at full load and light load conditions. the MAX17631AATE has a very low minimum on-time, which allows for a high switching frequency and a small solution size.

The MAX17631AATE's feedback voltage regulation accuracy is ±1.2% over the -40°C to +125°C temperature range. The device is available in a 16-pin (3mm x 3mm) TQFN package. Simulation models of the device are available.

• 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?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
