I. MPS Buck-Boost Modules

MPS buck-boost modules are non-isolated, general-purpose power supply modules designed to accommodate input voltage fluctuations and scenarios requiring switchable high or low input and output voltages. Compatible with buck, boost and buck-boost operating modes, they perfectly address the challenge that traditional single-function buck or boost chips face in adapting to wide dynamic input voltage ranges, making them an extremely versatile power supply solution.

1. Key Technical Features

This series of modules utilises MPS’s proprietary adaptive buck-boost topology, integrating power MOSFETs, inductors, compensation circuits and control logic into a fully integrated package design, enabling independent operation without the need for complex external components. The modules support an ultra-wide input voltage range, covering a variety of voltage scenarios such as low-voltage battery power supplies, industrial regulated power supplies and fluctuating in-vehicle power supplies. They can automatically switch operating modes when the input voltage is higher than, lower than or equal to the output voltage, maintaining a stable output voltage throughout without mode-switching ripple or output voltage drop issues.

Furthermore, the module incorporates high-efficiency synchronous rectification technology, which significantly reduces switching and conduction losses. It maintains high conversion efficiency under both light and heavy load conditions, effectively reducing the device’s power consumption and heat generation. It features built-in comprehensive protection mechanisms against overcurrent, overvoltage, overheating and short circuits, ensuring excellent adaptability to operating conditions and operational stability.

2. Key Product Advantages

- Highly integrated, minimalist design: A single module integrates all core power and control components, eliminating the need for external inductors or power transistors. This significantly reduces PCB footprint, simplifies power supply architecture design, and lowers wiring complexity and material costs.

- Wide-voltage dynamic adaptation: Overcoming the voltage adaptation limitations of traditional power modules, it handles complex operating conditions such as battery discharge voltage drops, in-vehicle voltage fluctuations and minor grid voltage variations, whilst consistently maintaining a stable output voltage.

- High Efficiency and Low Heat Generation: A synchronous rectification topology combined with an optimised switching algorithm achieves a conversion efficiency of over 95% at full load, whilst power consumption is extremely low at light loads, making it suitable for devices requiring long-term standby or continuous operation.

- High Reliability Protection: Integrated with multiple intelligent protection functions, it automatically limits current and cuts off power in abnormal conditions to prevent damage to both the downstream load and the module itself, thereby enhancing the overall stability of the equipment.

3. Typical Application Scenarios

Widely used in lithium-ion battery-powered equipment, portable smart devices, in-vehicle electronic equipment, industrial IoT sensors, smart home devices, low-voltage industrial control modules and similar applications; particularly suited to small- and medium-power power supply systems where the input voltage fluctuates dynamically but a stable, fixed output voltage is required.

II. MPS Isolated DC/DC Modules

MPS isolated DC/DC modules are specialised power supply modules designed to meet requirements for electrical safety isolation, interference immunity and isolation between high- and low-voltage systems. Utilising MPS’s proprietary high-voltage capacitive isolation technology, they achieve complete electrical isolation between input and output, thoroughly blocking the high- and low-voltage circuits and suppressing common-mode interference. They serve as core power supply solutions for industrial, medical and high-voltage equipment.

1. Key Technical Features

The core advantage of this series of modules is complete electrical isolation, with an isolation withstand voltage of up to 5 kV rms. They feature an ultra-high standard of common-mode transient immunity (CMTI), with a rated value exceeding 100 kV/µs, enabling them to effectively withstand high-frequency interference, voltage spikes and electrostatic discharges in industrial environments, thereby ensuring the stable operation of downstream low-voltage precision circuits. The modules integrate an isolated gate driver, power switch, isolated transmission unit and voltage regulation circuit, eliminating the need for external isolation components and providing a one-stop isolated power supply solution.

Compared to traditional optocoupler and transformer isolation solutions, MPS’s capacitive isolation technology offers short propagation delay, low pulse width distortion and minimal temperature drift, balancing isolation safety with power supply accuracy whilst avoiding the drawbacks of traditional isolators, such as ageing, high power loss and bulky size. The module supports a wide input voltage range and features precisely adjustable output voltage, making it suitable for a wide range of load requirements.

2. Key Product Advantages
