Mingjiada Electronics Supply TI Synchronous Buck Integrated Power Solution

In power supply design for industrial automation, automotive electronics, telecommunications equipment, servers and embedded hardware, integrated synchronous buck DC-DC solutions have become the mainstream choice for point-of-load (POL) power supplies, thanks to their high power density, minimal peripheral circuitry and excellent conversion efficiency. Shenzhen Mingjiada Electronics Co., Ltd. — a long-standing supplier of the full range of TI (Texas Instruments) integrated MOSFET synchronous buck converters and integrated power modules — also offers component recycling and part sourcing services, providing power engineers with a one-stop solution for procuring genuine components.

General-purpose industrial integrated FET synchronous buck converters
- TPS54360: A classic wide-voltage model from the SIMPLE SWITCHER® series, featuring 4.5V–60V input, 3.5A continuous output, integrated high-side and low-side MOSFETs, support for adjustable switching frequency, an Eco-mode energy-saving function for light loads, and a wide operating temperature range of –40°C to 125°C. Commonly used in industrial 24V bus systems and energy storage auxiliary power supplies.
- TPS54538: 3.8V–28V input, up to 5A output, peak current control, integrated loop compensation eliminating the need for external compensation components, integrated bootstrap capacitor, supports frequency synchronisation and spread-spectrum modulation to reduce EMI; suitable for industrial control boards and test equipment.
- LMQ66430: 3V to 36V input, 3A output, featuring MINT low-interference technology to optimise switching node ringing, supports spread-spectrum modulation, functional safety-compliant, compact VQFN package; the preferred choice for robotics and measurement equipment.
- LM76005: Ultra-wide 3.5V–60V input, 5A output, up to 98% duty cycle, supports pre-biased start-up and ‘Power Good’ (PG) signal, comprehensive protection; suitable for high-voltage industrial DC power supply systems.

Automotive-grade synchronous buck converters
- LM63440-Q1 / LM63460-Q1: Automotive-grade ZEN1 architecture, 3V–36V input, 4A/6A current options, HotRod™ QFN package to reduce parasitic inductance, switch frequency adjustable from 200kHz to 2.2MHz, AEC-Q100 certified, for powering in-vehicle infotainment systems and ADAS peripherals.
- TPS62903Q-Q1: 3–18 V input, 3 A output, micro VQFN package, low quiescent current, switchable switching frequency, suitable for in-vehicle sensors and small ECUs.

Low-voltage, low-current, high-frequency synchronous buck regulators (for portable devices, embedded systems, and FPGA/MCU power supplies)
- TPS62170: 2.7 V to 10 V low-voltage input, 0.5 A output, 2.2 MHz high frequency, small SOT package, ultra-low quiescent power consumption; suitable for portable devices and IoT modules.
- TPS62810: High-frequency, low Iq synchronous buck regulator with output current ranging from 0.5A to 3A; available in a micro-package; specifically designed for point-of-load power supply to FPGAs, MCUs and SoCs.

Integrated Inductor Power Module
The TPSM series (e.g. TPSM65610) integrates a controller, MOSFET and inductor into a single package, significantly reducing the number of components on the BOM. The MagPack package enhances thermal performance and shortens power supply development cycles, making it suitable for high-density power boards in servers and telecommunications equipment.
