Recycle MPS LED Drivers:AC-DC Lighting,DC-DC Lighting & Backlight,Automotive Lighting

The MPS LED driver product range covers three major application areas: AC-to-DC lighting, DC-to-DC lighting and display backlighting, and automotive-grade lighting. With features including high integration, low EMI, multiple dimming options and comprehensive protection, these drivers are suitable for applications such as domestic lighting, industrial backlighting, in-vehicle pixel headlights and ambient lighting, making them mainstream power management devices in lighting power supply solutions. Shenzhen Mingjiada Electronics recycles idle chips and obsolete stock, catering to both component procurement and the need to realise the value of inventory assets.

I. Product Details
1. AC-DC LED Drivers for Lighting
MPS AC-DC LED drivers are specifically designed for mains-powered lighting solutions. Featuring built-in PFC (Power Factor Correction) and primary-side/secondary-side constant-current control, they are suitable for panel lights, downlights, floodlights and commercial lighting fixtures. They support a wide range of mains input voltages and meet Chinese national standards for harmonics and power factor.
Key features: Integrated high-voltage start-up circuit and valley-start technology to reduce switching losses; supports analogue dimming and PWM dimming; features open-circuit, short-circuit, overtemperature and overcurrent protection; simplifies the peripheral BOM, reduces the number of components such as optocouplers, and minimises the PCB footprint of the luminaire.
Typical model categories: primary-side feedback constant-current drivers, high power factor (PF) drivers with PFC, and isolated/non-isolated solutions, covering power ranges from low-power domestic lighting to medium- and high-power industrial lighting.
Applications: indoor LED lighting, outdoor landscape lighting, and commercial ceiling lighting.

2. DC-DC LED Drivers for Lighting and Backlighting
This series comprises low-voltage DC-input LED drivers, including WLED backlight drivers and multi-channel constant-current drivers, designed for DC-powered lighting applications such as display backlights, industrial control panels, portable devices and strip lights.
Key features: Primarily utilising buck, boost and buck-boost topologies, offering high energy efficiency and excellent thermal performance; multi-channel independent constant-current output with high current matching accuracy; supports high-frequency PWM dimming with no flicker; compact packaging suitable for compact display modules; certain models integrate soft-start and LED open-circuit and short-circuit detection.
Typical applications: LCD/OLED display backlighting, industrial displays, instrumentation backlighting, equipment indicator lights, and low-voltage strip lighting.

3. Automotive Lighting: AEC-Q100 Automotive-Grade LED Drivers
All MPS automotive-grade LED drivers are developed in full compliance with AEC-Q100 automotive certification; some solutions support ISO 26262 functional safety design, covering interior ambient lighting, reading lights, tail lights, brake lights, matrix headlights and pixel headlights. They are categorised into two main types: single-channel high-power drivers and multi-channel array drivers.
Key features: Low-EMI design, suitable for the demanding electromagnetic environment of automotive applications; a wide range of dimming interfaces, including PWM, UART and Adaptive Current Feedback (AFC); built-in fault diagnosis for individual LEDs, including open-circuit, short-circuit, overheating and undervoltage protection; wide automotive-grade input voltage range, capable of withstanding battery load dump transients; Multi-channel models allow independent control of each LED channel, supporting dynamic lighting effects and animated flowing effects, such as the MPQ7228-AEC1 16-channel sink-current LED driver, the MPM6010-AEC1 integrated power module, and the MPQ2484U-AEC1 multi-topology LED controller.
Applications: External automotive headlights, tail lights and daytime running lights; interior RGB ambient lighting, door handle lighting and in-vehicle IR fill lighting.

II. Buyer’s Guide
Key Considerations for Selection
1. Determine the input source: For 220V mains lighting, prioritise AC-DC drivers; for battery or DC power supply, and screen backlighting, select DC-DC backlight drivers; For 12V/24V in-vehicle lighting, automotive-grade models bearing the AEC-Q100 mark must be selected; industrial-grade components cannot be used as substitutes for automotive-grade components.
2. Current and Channels: For single high-power LEDs, select a single-channel high-current driver; for pixel lights, RGB ambient lighting and multi-zone backlighting, prioritise multi-channel constant-current ICs, paying close attention to current matching accuracy between channels.
3. Dimming Requirements: For standard luminaires, prioritise PWM dimming; for high-end automotive dynamic lighting, prioritise models with UART and digital communication interfaces; medical and camera backlighting requires high-resolution, low-frequency dimming to avoid flicker.
4. Compliance Requirements: For luminaires intended for export, verify compliance with PFC and harmonic standards; for automotive projects, verify AEC-Q100 grades, EMI specifications and functional safety levels.
5. Packaging and Thermal Management: For high-power solutions, prioritise the evaluation of heat sinks and packaging thermal resistance; integrated module solutions can shorten the development cycle.

Procurement and Inventory Management Recommendations
When procuring, prioritise verification of batch numbers, packaging and original condition; for automotive-grade components, verify the grade specified in the datasheet; MPS driver ICs are prone to becoming dead stock following project completion or design changes; long-term idling poses risks of discontinuation, depreciation and moisture ingress in packaging. Please contact Mingjiada Electronics to assess recycling and monetisation options.
Supplier selection: prioritise suppliers capable of providing datasheets, factory documentation and sample support. Mingjiada Electronics supplies the full range of genuine MPS LED driver components, supporting samples, small batches and bulk orders.

III. Mingjiada Electronics’ Electronic Component Recycling Process
Mingjiada Electronics specialises in the long-term recycling of original, surplus electronic components, factory stock and distributor surplus stock. We only accept materials sourced legally, which are original, have not been installed in equipment and are in intact packaging. Our process is transparent, and we sign non-disclosure agreements to protect clients’ project information.

1. Submit a Bill of Materials: Clients compile a list of materials to be recycled, specifying the model, brand, quantity, batch number, package type and packaging condition, and attach photographs of the actual items. This is submitted to the evaluation team via email or online channels.
2. Professional Evaluation and Quotation: The evaluation team takes into account real-time market conditions, model scarcity, material shelf life and packaging integrity, and generally provides a preliminary recycling quotation within 24 hours.
3. Sample Verification / On-site Inspection: For small batches, samples may be sent for testing; for large-volume stock in the Pearl River Delta and elsewhere in China, staff can be arranged to visit the premises for stock-taking and inspection, verifying vacuum packaging, moisture-proof labels, silk-screen printing and batch numbers, whilst distinguishing between automotive-grade and industrial-grade materials.
4. Confirmation of Transaction and Signing of Agreement: Both parties confirm the price, sign a purchase and sale contract, sign a non-disclosure agreement as required, and agree on the method of collection.
5. Material Handover and Settlement: We arrange for collection from your premises or for you to dispatch the goods. Following re-inspection upon receipt and confirmation that everything is in order, payment is settled in cash via the agreed method; we support corporate bank transfers, thereby completing the transaction.
