Mingjiada Electronics Supplies TI Converter Products: Analysis of Synchronous Buck and Boost Converter Models

Shenzhen Mingjiada Electronics Co., Ltd. — a long-term supplier of a full range of high-reliability TI power converters to the market, including synchronous buck converters and synchronous boost converters, catering to diverse needs from low-power portable devices to high-power automotive systems.

 1. TI Synchronous Buck Converters: A Model of High Efficiency and Compact Size

Synchronous buck converters (Buck Converters) significantly reduce the conduction losses of traditional diodes through synchronous rectification technology, thereby improving efficiency and reducing heat generation.

Mingjiada Electronics supplies the following models:

LM73605QRNPRQ1 - Automotive-grade 5A high-efficiency buck solution

Specifically designed for automotive electronics, it supports a wide input voltage range of 3V to 36V, easily handling voltage fluctuations during vehicle start/stop or sudden load drops. Its 5A continuous output current capability can directly drive high-power modules such as ADAS cameras and in-vehicle processors, and it is certified to AEC-Q100 Grade 1 (-40°C to +125°C operating temperature), making it suitable for extreme environments such as engine compartments. The device features a configurable switching frequency up to 2.2MHz, combined with a compact inductor design, significantly optimising EMI performance.

TPS563201DDCR - Compact 3A Universal Converter

Targeted at space-constrained applications such as digital TVs and set-top boxes, it adopts an ultra-small SOT-23-6 package, supporting 4.5V to 17V input and 3A output current. Its fixed switching frequency of 570kHz, combined with an internal compensation circuit, simplifies peripheral design and achieves up to 95% efficiency. It also includes built-in overcurrent protection and thermal shutdown functions to ensure stable operation over extended periods.

LM63615 Series (DQDRRRQ1/CAQDRRRQ1) - Flexible and Configurable Automotive Solution

Supports 1.5A output with an input voltage range of 3.5V to 36V. Its unique feature is its pin-programmable capability: by configuring the pins, the output voltage (3.3V/5V/1V-20V adjustable), switching frequency (400kHz/2.1MHz/250kHz-2200kHz), and operating mode (FPWM/auto) can be set, significantly enhancing design reusability. Its WSON package (10mm²) is optimised for space-constrained automotive instrument panels or body control units.

II. TI Synchronous Boost Converter: High Power Density and Wide Voltage Adaptability

Synchronous boost converters (Boost Converters) are critical in battery-powered devices. TI achieves a balance between 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 lithium battery input), supporting a wide input range of 2V-18V, perfectly compatible with single/dual-cell lithium batteries or supercapacitors. This device integrates a 6.5mΩ high-side MOSFET and an 8.5mΩ synchronous rectifier, achieving peak efficiency of up to 96.9%. Its SOO modulation technology enables seamless switching between PWM and PFM modes, improving light-load efficiency by over 15%. The package uses a miniature QFN (2.5×3mm), suitable for Bluetooth speakers, USB PD fast-charging modules, and portable medical devices.
