Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS92602BQPWPRQ1 device is a single and dual channel high side current LED driver. With full protection and diagnostics, this series of devices is specifically and ideally suited for automotive headlamps. At the bottom of each individual driver is the peak current mode boost controller. Each controller consists of two separate feedback loops, a current feedback loop with a high-side current sense tap and a voltage feedback loop with an external resistor divider network. This controller transmits a constant output voltage or a constant output current. The connected load determines whether the device regulates a constant output current (if the circuit reaches the current set-point before the voltage set-point) or a constant output voltage (if the circuit reaches the voltage set-point is reached first), e.g. under open circuit load conditions). The output voltage can be regulated by the circuit if the circuit reaches the voltage set-point first (if the voltage set-point is reached first), e.g. under open load conditions.

• 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.
