Mingjiada Electronics Supply TI TPSM82821 5.5V/1A High Efficiency Step-Down Converter MicroSiP™ Power Module
In space-constrained designs such as portable electronics, Internet of Things (IoT) devices and industrial sensors, the miniaturisation and high efficiency of power modules are often critical to the success of a solution. Mingjiada Electronics has long supplied TI’s (Texas Instruments) TPSM82821 high-efficiency buck converter MicroSiP™ power module, providing a highly integrated, design-friendly power solution for low-voltage, low-to-medium current buck applications.
Product Overview
The TPSM82821 is a MicroSiP™ step-down power module launched by TI, which integrates a synchronous step-down converter and a power inductor, with a continuous output current capability of 1A. The device supports input voltages ranging from 2.4V to 5.5V, with an output voltage adjustable between 0.6V and 4V, and a typical switching frequency of 2.25MHz. Thanks to MicroSiP™ packaging technology, the TPSM82821 measures just 2.0 mm × 2.5 mm × 1.1 mm, making it ideal for compact designs with strict board space constraints.
Compared to discrete buck solutions, the TPSM82821 integrates the inductor within the module; the design requires only a small number of input and output capacitors and a feedback resistor, significantly shortening the development cycle, reducing BOM complexity, and minimising the risk of power supply noise caused by layout and routing.
Key Features and Benefits of the TPSM82821
MicroSiP™ High Integration: Integrates an inductor and a synchronous buck converter, reducing the number of external components and PCB footprint, making it suitable for space-constrained applications such as wearable devices and sensor nodes.
High-Efficiency Buck Conversion: Utilises a synchronous rectification topology and the DCS-Control™ architecture, achieving efficiency of approximately 95% under typical conditions, which helps reduce system heat generation and extend battery life.
1A Output Capability: Meets the power requirements of microcontrollers, wireless modules, sensors, memory and small-to-medium power digital loads.
Low Quiescent Current and Power-Saving Mode: Supports a power-saving mode under light load conditions, with a typical quiescent current of approximately 15µA, helping to reduce standby power consumption.
Wide output voltage range: The output voltage is adjustable within the range of 0.6V to 4V, making it suitable for a variety of low-voltage power rail designs.
Compact size and high reliability: Featuring a 2.0mm × 2.5mm × 1.1mm MicroSiP™ package with an operating temperature range of -40°C to 125°C, it is suitable for both industrial and consumer environments.
Typical Applications
The TPSM82821 is suitable for a wide range of low-voltage, low-to-medium-current step-down applications where space is limited, including:
Portable and wearable devices: smart watches, fitness trackers, portable medical monitoring devices
