Traco Power Switching Regulator, SIP3 Package, 5W Power Rating - TSR 1 Series - TSR 1-2450

Is your power supply's voltage too high for your equipment? Turn it down with this Traco Power switching regulator. As it switches inputs between 6.5 and 36V DC to a 5V DC load, it's a go-to choice for dialling down standard electrical supplies. Thanks to its ±0.2% line regulation rating, the unit's output stays steady to keep its system running without a hitch. Slotting the device onto a PCB is no issue as it fixes using simple through-hole mounting. By converting up to 94% of its input voltage, the component pulls the plug on power waste to make for energy-efficient switching.

Features & Benefits

• Maximum ripple voltage of 50mV to Block out disruption to power connections from noise

• Plastic and silicone body for effective insulation against hazardous electrical loads

• Integrated short-circuit protection automatically restarts after faults, cutting back on downtime

• Responds to load changes in 250μs, so it keeps up with unstable power supplies

Applications

• Automotive industry

• Domestic appliances

• Robotics systems

Do I need to mount a heat sink to use this product?

No, this regulator's high conversion efficiency means it cuts down on heat generation, so there's no need to fit a heat sink.
