Leveraging its global warehouse network and professional technical team, Mingjiada offers a one-stop service including genuine product guarantees, fast delivery, and solution design.

Core Products and Technical Advantages

The Microchip power management chips supplied by Mingjiada Electronics are renowned for their high efficiency and reliability, primarily covering four major product lines:

DC-DC Converter Solutions  

Synchronous Buck Converters: Such as the MIC2288 series (4MHz switching frequency, efficiency up to 95%), supporting 3A output current, using a 2mm×2mm ultra-small package, meeting high-density power design requirements  

Wide Input Voltage Buck Controllers: The MIC2165 supports an input range of 4.5V to 60V, and when paired with an external MOSFET, enables flexible high-power design

Boost Converters: The MCP1640B has a static current of just 19μA and efficiency of 93%, making it ideal for battery-powered portable devices

High-Performance LDO Linear Regulators

High-Current Models: The MIC29302 provides 3A output with an ultra-low voltage drop of 350mV@3A, suitable for processor core power supply

Ultra-low noise models: The MIC5317 series offers PSRR of 75dB @ 1kHz and output noise of 30μV RMS, meeting the requirements of RF and precision instruments

Automotive-grade products: The TC1262 series, certified to AEC-Q100, operates at temperatures from -40°C to +125°C, suitable for in-vehicle infotainment systems and ADAS modules

Smart power management systems

Digital enhanced PMIC: Supports I2C interface programming, such as the MCP19111, which can dynamically adjust control parameters to optimise system energy efficiency

Multi-channel power management: Integrates 3-5 power rails to simplify power supply design for complex systems such as in-vehicle camera modules and industrial HMIs

Battery management and power devices

Battery protection IC: Supports charging, discharging control, and battery level monitoring for multi-cell lithium batteries, extending the battery life of IoT devices

Power MOSFET: Low on-resistance and fast switching characteristics for high-efficiency power conversion topologies

Microchip power management chips supplied by Mingjiada Electronics are widely used in:

Industrial automation: Provides reliable power solutions for PLCs, HMIs, and servo drives, meeting EMC requirements

Automotive electronics: Models certified to AEC-Q100 standards can be used in in-vehicle infotainment systems, ADAS, etc.

Communication Equipment: High-switching-frequency products (e.g., MIC2288) are suitable for space-constrained applications such as 5G small cells

Consumer Electronics: Ultra-low static current models extend battery life in portable devices
