Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS92515/TPS92515-Q1 2A LED drivers are compact monolithic switching regulators with an integrated low resistance N-channel MOSFET. The devices are intended for use in high brightness LED lighting applications where high efficiency, high bandwidth, PWM and/or analogue dimming and small size are emphasized. The regulator operates with constant off time and peak current control. Operation is simple: after an output voltage based off time, the on time starts. Conduction ends when the peak inductor current threshold is reached. The TPS92515/TPS92515-Q1 devices can be configured to maintain a constant peak-to-peak ripple during the on and off cycles of the shunt FET dimming cycle. This is ideal for maintaining a linear response over the entire shunt FET dimming range. The TPS92515 and TPS92515-Q1 devices operate over a voltage input range of up to 42 V. The TPS92515HV and TPS92515HV-Q1 have a high voltage option with a voltage input range of up to 65 V. The TPS92515-Q1 devices are AEC-Q100 compliant for automotive 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.
