Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LM5168FQDDARQ1 synchronous buck converter is designed to regulate over a wide range of input voltages to minimise the need for external surge suppression components. 50ns minimum controllable on-time facilitates a large step-down conversion ratio and supports direct step-down conversion from a nominal 48V input to the low voltage rail, reducing system complexity and solution cost. The LM5168FQDDARQ1 is capable of operating at nearly 100% duty cycle as needed during input voltage dips down to 6V, making it ideal for industrial and high-cell-count battery pack applications with a wide input supply voltage range.

• 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.
