As a strategic partner of Renesas in the Asia-Pacific region, Shenzhen Mingjiada Electronics Co., Ltd. has built an agile supply network covering all fields of PMics including automotive-grade, industrial Internet of Things, and consumer electronics. With genuine products from the original factory, in-depth technical collaboration, and global ultra-fast delivery, it empowers customers to overcome the challenges of complex power supply architecture design!
The Renesas multi-channel PMIC, a core supply of Mingjiada
1. A full-scenario product matrix precisely matches system-level energy supply demands
Intelligent cockpit power supply center
RAA215300 (12-channel output) : Supports ASIL-B functional safety, integrates CAN FD wake-up and 40V drop load protection, providing 0.5% accuracy nuclear voltage/memory voltage for 8155 cockpit SoC;
ISL78264 (AEC-Q100 certified) : Operates in the full temperature range of -40℃ to 125℃, dynamically adjusts the DDR5 memory voltage (0.5V to 1.2V), and meets the failure diagnosis requirements of ISO 26262.
Industrial Internet of Things Energy Manager
DA9131 (Dual-channel 4A/97% efficiency) : Supports ultra-low standby of <2μA, and is equipped with solar MPPT algorithm to provide 10 years of maintenance-free power supply for LoRa sensors.
RAA223015 (Multi-Protocol Communication Power Supply) : Integrated I²C/SPI bus control, customizing 12V/5V/3.3V isolated power trees for RS-485+ Bluetooth dual-mode gateways.
Miniaturization solution for consumer electronics
DA9213 (4×3mm WLCSP package) : 2.5A dual-channel Buck converter, switching frequency 6MHz, eliminating inductance whistling in TWS earphone charging cases;
ISL9122 (Dynamic Voltage Regulation) : 0.5V step accuracy matches the DVFS strategy of the Snapdragon 8 series processor, increasing the battery life of AR glasses by 15%.
2. Original factory traceability guarantee, automotive-grade quality control standards
Provide Renesas complete batch traceability codes, wafer fab test reports and AEC-Q100/ISO 26262 compliance certificates;
Triple limit verification is carried out before storage:
The parameter drift (ΔVout<±1%) of the automotive-grade PMIC was verified after 1000 hours of high-temperature aging at 150℃.
The industrial-grade model has passed the 10kV ESD impulse and IEC 61000-4-5 surge tests.
3. Global inventory hub, rapid response for scarce models
Shenzhen bonded warehouse always keeps over 80 main models (such as RAA215300/DA9131) in stock, with 24-hour delivery (next-day delivery to Beijing-Tianjin-Hebei region/Greater Bay Area).
Rare automotive-grade models (such as ISL78264) are directly dispatched from the Tokyo branch via DDP, and customs clearance and delivery are completed within 8 working days.
Mingjiada offers a minimalist procurement process
Request submission: Send the model list (e.g. RAA215300) to sales@hkmjd.com, indicating the number of output channels/certification level.
Real-time delivery: Price and inventory feedback within 1 hour. Alternative solutions are provided for scarce models (such as DA9213→DA9215).
Inspection and delivery: In the Pearl River Delta region, delivery can be made as fast as within 24 hours, and in other cities, delivery is generally available within 48 hours.
