Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS92530QPKDRQ1 is a monolithic 3-channel synchronous step-down LED driver with a wide operating input voltage range of 4.5V to 65V that can independently power three strings of LEDs connected in series.The TPS92530-Q1 implements an adaptive on-time averaging current-mode control function and is designed to produce either a constant voltage or a constant current output. The adaptive on-time control provides a nearly constant switching frequency with settings from 100kHz to 1.2MHz. In constant-current mode, the device is compatible with shunt FET dimming technology and dynamic beam headlamps based on LED matrix managers. In constant voltage mode, the adaptive on-time control feature supports high bandwidth operation and provides fast transient response. Inductor current sensing and closed-loop feedback provide better than ±4% accuracy over a wide range of input voltage, output voltage, and ambient temperature.

In constant-current mode, the high-performance LED driver can individually modulate the LED current using analogue dimming or PWM dimming techniques. A linear analogue dimming response greater than 16:1 can be achieved by programming the 10-bit reference (CHxREF) via SPI. PWM dimming of the LED current is achieved by directly modulating the corresponding UDIM input pin with the desired duty cycle or by enabling the internal PWM generator circuitry. The PWM generator converts the 10-bit PWM register value into the corresponding duty cycle by comparing the value of the 10-bit PWM register with a programmable digital counter.

Applications

Automotive headlight and adaptive LED driver modules

• 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.
