Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS92691QPWPRQ1 is a general purpose LED controller that supports a range of boost or buck driver topologies. The device implements fixed frequency peak current mode control technology, programmable switching frequency, ramp compensation and soft start timing. A high voltage (65V) rail-to-rail current sense amplifier is incorporated, allowing direct measurement of LED current using either high-side or low-side series sense resistors. The amplifier can be used to achieve low input offset voltages and better than ±3% LED current accuracy over the 25°C to 140°C junction temperature range and 0 to 60V output common mode voltage range.

Applications

TPS92691-Q1: Automotive exterior lighting applications

Architectural lighting and general lighting applications

• 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.
