Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS62822DLCR is a versatile and easy to use synchronous step-down DC/DC converter with a very low quiescent current of only 4µA. The device has an input voltage of 2.4V to 5.5V and can deliver up to 3A of output current (TPS62823). The product is based on the DCS-Control™ topology for fast transient response.

With an internal reference, the output voltage can be regulated down to 0.6V with up to 1% feedback voltage accuracy over a junction temperature range of -40°C to 125°C. The 1A/2A/3A scalable pin-to-pin device family is BOM-to-BOM compatible and can be used in combination with small 470nH inductors.

The TPS62822DLCR automatically enters power saving mode at ultra light loads and maintains high efficiency.

The device features a power-on signal and internal soft-start circuitry. It is capable of operating in 100% mode. For fault protection, it incorporates intermittent current limiting and a thermal shutdown function.

The TPS62822DLCR is available in a 2 x 1.5mm QFN-8 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?

  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.
