Da Lian Dajia Group Launched A 28W Car LED Lighting Solution Based On Microchip And AMS OSRAM Products

On August 15, 2024, the international leading semiconductor component distributor dedicated to the Asia-Pacific market-Da Lianda University Holdings announced, Its Pinjia launched a micro -core technology (MICROCHIP) MCP19117 PWM controller and AMS OSRAM KW3 HNL631.TK LED 28W car LED lighting solution.

In the automotive industry,The LED lighting system is gradually becoming the mainstream trend.Compared with the traditional halogen headlights or sorchium headlights, LED lighting has higher brightness, lower energy consumption and longer life span? These advantages have continuously increased the market share of LED headlights.In automotive applications, the LED headlights can not only improve driving safety, but also provide a brighter and more uniform lighting effect, to enhance the comfort and convenience of driving.In this trend, Da Lian Da Pinjia is based on Microchip MCP19117 PWM controller and AMS OSRAM KW3 HNL631.TK LED to launch a 28W car LED lighting solution, which can help realize the automatic automotive lighting design of functionality and security.

MCP19117 is a digital enhanced power simulation (DEPA) PWM controller under Microchip. It integrates 8 -bit PIC microcontroller and can make the performance of high -speed simulation solutions (including high efficiency and fast transient response) and digital solution.The combination of configurable and communication interfaces can maximize the advantages of each technique, thereby creating a more cost -effective, configurable, and high -performance power conversion solution.Not only that, users can also program the device to make a dynamic response to the measurement or events in the system to achieve steady operation.In addition, MCP19117 has a calibration function, which can improve accuracy and measure performance, and equipped with large -capacity flash memory, which can store more code in the device.

Microchip's unique DIGTAL Enhanced Power Analog series highly integrated PWM power module, which can be set with various settings with MCA with MCC with free software, such as working frequency, output voltage, output current, and protection mechanism.In addition, because the device is equipped with an 8 -bit PIC12 MCU, the use of program assistance can achieve more elastic applications, such as the temperature sensor of the temperature with accuracy ± 1 ℃ MCP9700A for precise temperature control and protection;The control of the upper, like a short time highlightLighting, flashing, frequent flashes, etc.

KW3 HNL631.TK is a member of AMS OSRAM OSLON BLACK FLAT X product series. With its excellent performance and cost benefits, KW3 HNL631.tk is becoming an ideal light source for high cost -effective lighting solutions.

In addition, in terms of communication, this solution is still equippedMicrochip's ATA663211-GAQW Lin transceiver interface has further enhanced the interaction and control of the car.Thanks to the use of aluminum substrate and Lin communication design, this plan has great flexibility and excellent heat dissipation, which can ensure the stability and long -term operation of lighting.
