Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The power management integrated circuits (PMics) of Renesas Electronics Corporation can achieve various functions required by the power supply of the host system. PMIC can integrate the following functions: DC/DC conversion, battery charging, linear voltage regulation, power sequencing and other system power functions.

Renesas' PMIC product portfolio includes parallel regulators, point-of-load (POL) converters, power factor correction (PFC) power ics, multi-output controllers for XScale processors, and three-terminal regulators. At the same time, there are also ultra-small and highly efficient PMics, which are very suitable for consumer electronic devices such as smart phones, tablet computers, solid-state drives, network devices and wireless Internet of Things devices, industrial equipment and networked devices. In addition, Renesas also offers power management integrated circuits (PMics) tailored to specific application scenarios, suitable for various in-vehicle devices such as automotive TFT displays, ultrabooks, laptops, and tablet computers, as well as consumer electronics, industrial equipment, and networked devices. Renesas' PMIC products also include wireless charging integrated circuits suitable for the wearable device market.

As a well-known global electronic component distributor, Shenzhen Mingjiada Electronics Co., Ltd. relies on a inventory of tens of millions of yuan in stock to core supply Renesas' full range of multi-channel PMIC products, covering all scenario demands from ADAS smart cameras to central gateways and smart cockpits. It helps automakers and Tier 1 suppliers overcome power supply design challenges Accelerate the intelligent transformation.

I. Renesas PMIC Product Matrix: High integration, high Security, and full coverage of all scenarios

Mingjiada supplies Renesas with four major categories of multi-channel PMics, meeting the strict standards of automotive electronics with original factory quality

System-level power Management chip (SoC PMIC)

Representative model: RAA271000 (7 channels) + RAA271050 (Pre-regulator)

Technical features

The dual-chip collaboration achieves full-link voltage reduction from 12V to 0.8V, reducing power loss by 33% compared to traditional solutions.

It integrates a 12-bit SAR ADC for real-time monitoring of 16 external signals, eliminating the need for an independent ADC chip.

Supports ASIL D functional safety level (ISO 26262 certification), with built-in self-check and redundant monitoring mechanisms.

Typical applications: R-Car V3H/V4H ADAS camera system, autonomous driving domain controller.

2. Dedicated PMIC for gateways and domain controllers

Representative model: RAA271041 (Preadjuster) + RAA271005 (11 channels)

Technological breakthrough

Supports 2.5V cold start and 40V load drop to ensure the stable operation of the gateway under extreme voltage fluctuations.

The dynamic voltage-frequency Scaling (DVFS) technology reduces power consumption by 40% compared to the static solution, meeting the energy efficiency requirements of software-defined vehicles (SDVS).

The programmable spread spectrum clock reduces the EMI peak energy to 15dB, lowering the shielding cost.

3. Smart cockpit and in-vehicle camera PMIC

Star Model: RAA271082 (4-channel Integrated Solution)

Scenario-based design

▶ Single-chip integrated high-voltage step-down + dual-channel low-voltage step-down +LDO, supporting power supply for all mainstream in-vehicle image sensors;

Compliant with ASIL B safety standards, it is equipped with dual monitoring of OV/UV and CRC check to eliminate the risk of power failure for the camera.

Ii. Supply Service Advantages of Mingjiada: From genuine product guarantee to full-cycle empowerment

Facing the extreme reliability requirements of automotive electronics, Mingjiada has established a triple guarantee system:

1. Original factory genuine product guarantee

All PMics are purchased from Renesas' official channels and come with original factory packaging to ensure no refurbishment or substandard products.

2. Million-level inventory and agile delivery

Shenzhen-hong Kong dual warehouse synergy: The Shenzhen bonded warehouse (New Asia Guoli Building) and the Hong Kong constant temperature warehouse work in tandem, with the regular inventory of high-frequency models such as RAA271082 exceeding 50,000 pieces.

Emergency Response Network

▶ Small batch samples: Express delivery within 24 hours;

▶ Mass production orders: Supports VMI inventory management, 72-hour global DDP door-to-door delivery (covering automotive clusters in Europe, America and Southeast Asia)
