Supply TI Converter IC, Mingjiada Supply TI Synchronous Buck / Boost Converter
Shenzhen Mingjiada Electronics Co., Ltd. — Long-term provider of a comprehensive range of high-reliability TI power converters, including: synchronous buck converters and synchronous boost converters, catering to diverse requirements from micro-power portable devices to high-power automotive systems.
I. TI Synchronous Buck Converters: Exemplars of High Efficiency and Compact Design
Synchronous buck converters significantly reduce conduction losses associated with traditional diodes through synchronous rectification technology, enhancing efficiency and minimising thermal output.
Models supplied by Mingjiada Electronics:
LM73605QRNPRQ1 - Automotive-grade 5A high-efficiency buck solution
Specifically engineered for automotive electronics, it supports a wide 3V-36V input voltage range, effortlessly handling voltage fluctuations during vehicle start-stop cycles or sudden load drops. Its 5A continuous output current capability directly powers high-power modules such as ADAS cameras and in-vehicle processors. Certified to AEC-Q100 Grade 1 (-40°C to +125°C operating temperature), it is suitable for extreme environments like engine compartments. Featuring a configurable switching frequency up to 2.2MHz, this device significantly optimises EMI performance when paired with compact inductor designs.
TPS563201DDCR - Compact 3A Universal Converter
Targeted at space-constrained applications like digital televisions and set-top boxes, this solution utilises an ultra-small SOT-23-6 package supporting 4.5V-17V input and 3A output current. Its fixed 570kHz switching frequency, coupled with an internal compensation circuit, simplifies peripheral design while achieving up to 95% efficiency. Integrated overcurrent protection and thermal shutdown ensure stable long-term operation.
LM63615 Series (DQDRRRQ1/CAQDRRRQ1) - Flexible Configurable Automotive Solution
Supports 1.5A output with input voltage coverage from 3.5V to 36V. Its unique feature lies in pin-programmable functionality: configurable pins allow setting output voltage (3.3V/5V/1V–20V adjustable), switching frequency (400kHz/2.1MHz/250kHz–2200kHz), and operating mode (FPWM/auto), significantly enhancing design reusability. Its WSON package (10mm²) is optimised for space-constrained automotive instrument clusters or body control modules.
II. TI Synchronous Boost Converters: High Power Density and Wide Voltage Adaptability
Synchronous boost converters are critical in battery-powered devices. TI achieves a balance of high efficiency and low noise through fully integrated MOSFETs and intelligent modulation technology.
Key models supplied by Mingjiada include:
TPS61288LRQQR - 18V/15A ultra-high power density boost chip
Industry-leading 40W output capability (single-cell Li-ion input), supporting a wide 2V-18V input range, perfectly suited for single/dual-cell Li-ion batteries or supercapacitors. This device integrates a 6.5mΩ high-side MOSFET and an 8.5mΩ synchronous rectifier transistor, achieving peak efficiency of up to 96.9%. Its SOO modulation technology enables seamless switching between PWM and PFM modes, enhancing light-load efficiency by over 15%. Packaged in a miniature QFN (2.5×3mm), it is suitable for Bluetooth speakers, USB PD fast-charging modules, and portable medical devices.
