Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS92518HVQPWPRQ1 device is a dual-channel step-down LED current controller with an SPI communication interface. The serial communication interface provides a single communication path for multi-channel and platform Lighting Driver Module (LDM) applications.The TPS92518HVQPWPRQ1 uses a quasi-hysteresis control methodology with a range of supported switching frequencies including a control method that supports switching frequencies from 1 kHz to 2 MHz. This control method enables excellent high-frequency parallel FET dimming and can also handle adaptive LED matrix-based headlight systems. Software-programmable SPI setpoints (precision peak current, controlled off-time, and output voltage detection) enable designers to develop a single LED driver solution for multiple load configurations that can be quickly reconfigured to meet the requirements of future LED driver designs.The TPS92518HVQPWPRQ1 is a high-voltage option with an input range of up to 65 V. The TPS92518HVQPWPRQ1 is a high-voltage option with a high input range of up to 65 V.

• 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.
