Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Amid the explosive growth of new energy vehicles, highly reliable power supply systems are becoming the lifeblood of overall vehicle safety. As a core electronic component supplier in the Asia-Pacific region, Shenzhen Mingjiada Electronics Co., LTD., relying on 20 years of experience in the automotive-grade chip supply chain and a stock network of tens of millions, provides a one-stop supply of Infineon's full range of power conversion chips and on-board charger (OBC) modules - with original factory direct supply quality, AEC-Q100 automotive-grade certification, and full-cycle technical empowerment Help customers overcome the energy efficiency challenges of 800V high-voltage platforms!

I. Infineon Technology Core: Redefining the "Energy Law" of Electric Vehicles

Power conversion chip: The "Efficiency Engine" of high-voltage platforms

The golden combination of SiC and IGBT:

CoolSiC™ MOSFET: Withstand voltage of 1200V, switching frequency increased by 5 times, OBC power density exceeding 4kW/L (40% higher than silicon-based solutions), loss reduced by 60%.

HybridPACK™ IGBT: Integrated with NTC temperature monitoring, it supports extreme operating conditions ranging from -40℃ to 175℃, reducing the heat dissipation cost for motor controllers by 30%.

Digital control core: The XMC4800 MCU is equipped with the EtherCAT bus to achieve nanosecond-level closed-loop control of the multiphase LLC resonant converter, with an efficiency of over 97%.

2. On-board Charger (OBC) : The "Smart Bridge" from Power Grid to Battery

Bidirectional Energy Cube

REF_3K6W_11S6P: 11kW bidirectional OBC module, supporting V2G/V2L functions, charging efficiency 95.5% (benchmarking against CCS standards);

Ai-driven optimization: Integrated with the OPTIGA™ Trust security chip, it dynamically adjusts the PFC strategy through machine learning, reducing the full charge time by 15%.

Electromagnetic compatibility king: EMC performance exceeds CISPR 25 Class 5 standards, radiation interference is reduced by 20dB, and the risk of central control screen flickering is eliminated.

Ii. Mingjiada Supply Matrix: Breaking the "Delivery Dilemma" of Automotive-grade Power Supplies

1. Original factory quality, zero-risk delivery

AEC-Q100 Full Certification: Each chip is provided with the original batch code from Infineon. It undergoes X-ray scanning and dynamic temperature chamber testing (-55℃ to 150℃) to ensure a defect rate of 0 ppm.

No worries about production halt: If the IGBT module is discontinued (such as IKW75N60T), it can be seamlessly switched to a compatible model (such as IKW75N65ES5).

2. Million-level automotive-grade stock, lightning-fast response

Strategic reserve of scarce models: Shenzhen Bonded Warehouse always keeps over 50 core material numbers of Infineon power supplies in stock, including

Power management IC: TLF35584 (Multi-output Safe power Supply)

OBC module: REF_3K6W_11S6P (11kW bidirectional)

SiC MOSFET: IMZ120R045M1 (1200V/45mΩ)

72-hour global delivery: Domestic orders are dispatched within 24 hours, and cross-border orders are delivered door-to-door (DDP terms + anti-static cold chain), which is three times faster than peers.

3. Deep technological empowerment to accelerate mass production and implementation

0-1 design support: Free provision of evaluation kits (such as OBC reference board REF_3K6W_11S6P) and PSpice simulation models;

Cost optimization at the tens of millions level: The order price for tens of thousands of pieces is 12% lower than the market price, supporting the VMI consignment inventory solution to relieve the cash flow pressure on customers.

Failure Analysis Laboratory: Offers PCB thermal simulation and EMC rectification reports, shortening the certification cycle by 50%.

Iii. Implementation Scenarios: From 800V Ultra-fast Charging to Smart cockpit power supply

800V high-voltage fast charging platform

Infineon CoolSiC™ MOSFET helps OBC achieve a power density of 4kW/ L. Combined with the digital control of XMC4800, it can charge 400km in 15 minutes (comparable to the Porsche Taycan architecture), reducing temperature rise by 35℃.

Intelligent cockpit multi-domain power supply

The TLF35584 multi-channel safety power supply chip, certified by ASIL-D, independently supplies power to the instrument panel, ADAS controller, and HUD system. With an isolation voltage of over 5kV, it eliminates black screen faults caused by inter-domain interference.

Electronic control of new energy commercial vehicles

The HybridPACK™ Drive IGBT module supports a continuous current of 700A and can withstand a temperature of 150℃ in the engine compartment, extending the lifespan of the electric bus's electronic control system to over 10 years or 1 million kilometers.

Act now and seize the commanding heights of electrification technology!

Whether it's the SiC solution that breaks through the bottleneck of 800V ultra-fast charging or the multi-domain power supply system that meets the ASIL-D safety level, Mingjiada, with Infineon power technology as its foundation, helps you redefine the "energy boundary" of new energy vehicles!
