Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS61280 synchronous boost converter power solution is suitable for products powered by Li-ion, nickel-rich, silicon anode, Li-ion or LiFePO4 batteries. The voltage range is optimised for single-cell portable applications such as smartphones or tablets. When the device is used as a high power front regulator, the TPS61280 extends battery runtime and breaks input current and voltage limits of the power supply system. In shutdown mode, the TPS61280 can operate in true straight-through mode, consuming only 3µA of quiescent current, thus extending battery life. During operation, when the battery is in a good state of charge, the low resistance, high efficiency integrated passthrough path connects the battery to the powertrain. If the battery reaches a low state of charge and its voltage falls below the minimum system voltage required, the device will seamlessly switch to boost mode to use the full battery capacity.

• 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.
