TI TPS82085 Buck Converter MicroSiP™ Module (3A High-Efficiency Buck Module with Integrated Inductor) | Mingjiada Electronics in Stock

TPS82085 Product Overview:

The TI TPS82085 is a 3A high-efficiency buck converter MicroSiP™ module introduced by Texas Instruments. Utilizing the DCS-Control™ topology, it integrates a synchronous buck converter and a power inductor into a miniature package, specifically designed for space-constrained, high-efficiency point-of-load (POL) power supply applications. Compared to traditional discrete buck solutions, the TPS82085 requires only a few external input and output capacitors and a feedback resistor to form a complete power supply circuit, streamlining the bill of materials (BOM) to just five components.

TPS82085 Key Features and Technical Advantages

MicroSiP™ integrated package significantly reduces PCB area

The TPS82085 integrates a buck converter IC and a power inductor into a thin µSiL package measuring 2.8 mm × 3.0 mm × 1.3 mm, resulting in significant savings in printed circuit board area compared to traditional discrete solutions. This package is suitable for automated assembly using standard surface-mount equipment, facilitating mass production.

DCS-Control™ Topology Balances Transient Response and Voltage Regulation Accuracy

The chip employs TI’s proprietary DCS-Control™ topology, delivering excellent load transient performance and precise output voltage regulation. The EN and PG pins support timing configurations for multiple power supplies, providing flexibility for complex system designs.

High Efficiency at Light Loads, Ideal for Battery-Powered Applications

Under light load conditions, the TPS82085 automatically enters a power-saving mode with a typical quiescent current of just 17 µA, helping to extend battery life in portable devices. Peak efficiency reaches 95%, and it maintains excellent energy efficiency even in the medium-to-high load range.

Multiple Protections Ensure Robust and Reliable System Operation

The chip integrates hiccup short-circuit protection, over-temperature protection, output discharge functionality, and an integrated soft-start feature that supports pre-biased startup, ensuring the power supply system operates safely under various abnormal conditions. It also complies with CISPR 11 Class B electromagnetic compatibility requirements, making it suitable for EMI-sensitive communications and industrial applications.
