Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Today, with the explosive iteration of gallium nitride fast charging, server power supplies and OBC for new energy vehicles, the synchronous rectifier controller, as the "core brain" for improving energy efficiency, its performance directly determines whether the power system can break through the 95%+ energy efficiency bottleneck. Shenzhen Mingjiada Electronics Co., LTD., as a seasoned electronic component distributor in the Asia-Pacific region, has established an agile supply chain covering the full range of Renesas digital control, adaptive, and automotive-grade synchronous rectifier controllers. With genuine products and global rapid delivery, it empower customers to create efficient, compact, and reliable power solutions.

Renesas is the leader in AC/DC RapidCharge™ solutions and supports more fast charging protocols than other suppliers. Renesas' zero-voltage switching (ZVS) technology, patented, offers an innovative digital approach that can reduce the size of 65W+ chargers by at least 30% compared to the brick-shaped adapters used in existing laptops, monitors, smartphones, power tools, and other portable products.

All AC/DC controllers of Renesas are hardwired devices, so fast chargers equipped with such controllers will not be hacked. Learn more about how the RapidCharge™ controller prevents fast chargers from being hacked.

The core advantages of Mingjiada

1. A full-scenario product matrix, precisely matching technological evolution

Digital Control Flagship

ISL6731 (supporting 2MHz switching frequency) : Integrated adaptive dead zone control, combined with GaN FET, can achieve a 65W PD fast charging solution with 98% efficiency;

RAA223021 (Multi-mode QR Control) : Supports CCM/DCM/QR working modes, providing ±1% load adjustment accuracy for server power supply.

Automotive-grade high-reliability solution

ISL78424 (AEC-Q100 certified) : Withstand 40V drop load impact, with full-temperature range driving capability from -40℃ to 150℃, providing a failure rate of less than 10ppm for 800V platform OBC.

RAJ306002 (Functional Safety ASIL-B) : Built-in MOSFET short-circuit diagnosis and under-voltage locking, meeting ISO 26262 functional safety standards.

Ultra-compact consumer electronics solutions

RAA230151 (SOT-23-6 package) : Quiescent current is only 45μA, compatible with 5W to 30W smart home power supplies, standby power consumption < 30mW;

ISL6751 (Self-powered Architecture) : No auxiliary winding required, simplifying the PCB layout of the TWS earphone charging case.

2. Original factory genuine product guarantee, zero-risk delivery

Provide the complete batch number of Renesas, factory test reports and RoHS/REACH compliance certificates;

Triple verification is carried out before warehousing:

The digital controller was verified for SPI communication stability through a temperature cycle ranging from -55℃ to 125℃.

The automotive-grade model has passed the IEC 61000-4-5 100A surge test and ISO 16750 vibration and shock test.

3. Global rapid response, agile allocation of scarce models

Shenzhen bonded Warehouse always keeps over 50 main models (such as ISL6731, RAA223021) in stock and ships within 24 hours.

Rare automotive-grade models (such as ISL78424) are transferred through the Tokyo branch warehouse and DDP customs clearance is completed within 7 working days.

The procurement process of Mingjiada Electronics

1. Requirements submission: Send the model list (e.g. ISL78424) to sales@hkmjd.com, indicating the package/certification level;

2. Real-time quotation: Feedback on price and delivery date within 1 hour. Alternative solutions are provided for scarce models (such as RAA223021→RAA223022).

3. Inspection and Delivery: Supports oscilloscope inspection in Shenzhen laboratory or video confirmation. Global cash on delivery by SF Express /DHL.

Whether it's the fast charging revolution in consumer electronics, the high-voltage leap in new energy vehicles, or the power upgrade in data centers, with our deep supply chain capabilities and power design experience, we ensure that every watt of electricity is transformed into the performance peak of our customers' products.
