Here’s an image of the TSR 1-2450 DC-DC converter from Traco Power—a compact SIP-3 module resembling a TO-220 footprint.

The TSR 1-2450 is a non-isolated, step-down (buck) switching regulator. Designed as a direct drop-in replacement for the classic 78xx linear regulators, it delivers enhanced efficiency and compact form factor.

• Highly Efficient: With efficiency up to ~96%, it runs cool without requiring heat sinks—ideal for thermal-sensitive designs.

• Easy Upgrade Path: Pin-compatible with traditional 78xx regulators, enabling quick retrofitting.

• Simplified Design: No need for external capacitors since filter capacitors are integrated.

• Robust Protections: Includes multiple protective features to enhance reliability.

• Compact SIP-3 Form Factor: Convenient for through-hole PCB designs, particularly where space is limited.

• Low Quiescent Use: Standby current is minimal, extending battery life in portable applications.

• Efficient replacement for 5 V linear regulators (on battery-powered or thermally constrained applications)

• Ideal for compact, high-density circuit designs requiring reliable, low-noise 5 V rails

• Suited for industrial control systems, embedded computing, telecom interfaces, or any design previously using LM7805 but seeking efficiency improvement

• Digi-Key lists the TSR 1-2450 with 6.5–36 V input and 1 A output, 5 W power, and 94% efficiency.

• Newark highlights improved accuracy (±2%), low standby current, and high efficiency enabling operation without heat sinks up to 60 °C ambient.

• TME includes physical specs, protections, and efficiency figures.

• TRC Electronics and other distributors list stock and pricing det
