TPS82130SILR 3A Power Module Specifications and Applications

ElecSuppliers Part Number GuideAug 15, 2026

TPS82130SILR is a compact step down power module from Texas Instruments designed to simplify DC to DC power supply implementation.

Unlike a conventional switching regulator IC that requires several external passive components, a power module integrates key components into a compact package. This can reduce the external component count and make the power supply section easier to implement on a PCB.

TPS82130SILR Power Conversion

TPS82130SILR is designed for 3A output current applications and operates as a synchronous step down converter.

A step down converter takes a higher DC input voltage and produces a lower regulated output voltage. This type of conversion is commonly required when processors, FPGAs, sensors or other digital devices operate at voltages below the main system supply.

The integrated approach of TPS82130SILR can be useful when board space is limited and a relatively simple power supply solution is preferred.

Why Use TPS82130SILR

One of the main advantages of a power module is reduced design complexity.

A conventional buck regulator normally requires an external inductor along with capacitors and other supporting components. TPS82130SILR integrates the power inductor with the regulator, allowing designers to reduce the number of external components around the power stage.

This can also make the PCB layout more compact.

For products with strict board space requirements, an integrated power module can therefore be an attractive alternative to a discrete switching regulator design.

TPS82130SILR Applications

TPS82130SILR can be considered for point of load power supplies and embedded electronic equipment.

Typical application areas can include industrial controllers, communication equipment, portable electronics, FPGA systems, processor power rails and other compact electronic products requiring regulated low voltage power.

The 3A capability also makes the device suitable for power rails with significantly higher current requirements than those served by small low current regulators.

TPS82130SILR Efficiency and Thermal Design

Power conversion efficiency is an important consideration when using a 3A power module.

Although an integrated solution can simplify the design, power losses still generate heat. The PCB therefore needs to provide an appropriate thermal path around the device.

Copper area, component placement and airflow can all affect the final operating temperature.

For higher current applications, thermal performance should be evaluated under the actual input voltage, output voltage and load conditions rather than relying only on the nominal current rating.

TPS82130SILR PCB Layout

The PCB layout of a switching power supply has a direct effect on performance.

The input and output capacitors should be positioned according to the manufacturer's layout recommendations, while high current paths should be kept appropriately short.

Grounding and thermal copper should also be considered during board design.

Because TPS82130SILR integrates the inductor, the layout can be simpler than a discrete buck converter design, but the switching power stage still requires careful PCB implementation.

TPS82130SILR Supplier Information

When searching for TPS82130SILR suppliers, buyers should use the complete part number to identify the intended Texas Instruments device.

Supplier quotations should be checked for the exact MPN, package, electrical specifications, product status and available quantity.

For an existing PCB design, an alternative power module should not be selected solely because it provides a similar output current. Input range, output voltage, switching characteristics, thermal behavior, footprint and control functions should also be compared.
