Overview

The TSRN 1-2450 is a non-isolated step-down switching regulator designed as a high-efficiency replacement for traditional 78xx series linear regulators. It provides a stable 5V output at up to 1A from a wide input voltage range of 6.5V to 36V. Its high efficiency of 91.5 percent eliminates the need for a bulky heatsink, making it ideal for space-constrained designs.

Why Choose This Part

The TSRN 1-2450 features a very low standby current of only 2mA and does not require external input or output capacitors for standard operation. It includes integrated short-circuit and over-temperature protection, ensuring robust performance in harsh commercial and industrial environments.

Applications

Linear Regulator Retrofitting
Drop-in replacement for LM7805 regulators in existing TO-220 footprints to reduce thermal load and improve efficiency.
Industrial Control Systems
Converting 24VDC industrial rails down to 5V logic levels with minimal power loss and high reliability.
Negative Output Circuits
Configurable for use in negative output voltage applications, providing versatility for bipolar power supply rails.
Battery Powered Equipment
Extends battery life in portable devices by minimizing wasted energy compared to linear regulation.

Getting Started

To use this module, simply solder it into a standard TO-220 footprint or 3-pin SIP layout. Ensure that the input voltage remains within the 6.5V to 36V range and note that no external heat sinking is required even at the full 1A load. For remote control functionality, the TSRN 1-2450A variant with angular pins or the SMD version can be used depending on the mechanical requirements.
