Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS54331DR device is a 28V, 3A asynchronous buck converter with an integrated high-side MOSFET featuring low R DS(on). To improve efficiency under light load conditions, the pulse-skipping Eco-mode feature is automatically activated. Additionally, the 1µA shutdown supply current makes this device suitable for battery-powered applications. Current-mode control with internal slope compensation simplifies external compensation calculations and reduces component count while allowing the use of ceramic output capacitors. A resistor divider programs the hysteresis for input under-voltage lockout. Overvoltage transient protection circuits limit voltage overshoot during startup and transient conditions. Cycle-by-cycle current limiting, frequency foldback, and thermal shutdown features protect the device and load under overload conditions. The TPS54331DR device is available in an 8-pin SOIC package and an 8-pin SO PowerPAD integrated circuit package, both of which are internally optimised to improve thermal performance.

• 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.
