The Tracopower TSR-1 series of step-down switching regulators are great replacement for linear regulators as they solve many power supply problems. These DC to DC converters are up to 96% more efficient with built-in capacitors and short circuit protection. Allowing full load operation up to +60°C ambient temperature without the need of any heat sink or forced cooling. The TSR-1 switching regulators provide other significant features over linear regulators. Providing better output accuracy (±2%), lower standby current of 2 mA and no requirement of external capacitors. The high efficiency and low standby power consumption makes these regulators an ideal solution for many battery powered applications.

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.

• 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

• Automotive industry
• Domestic appliances
• Robotics systems

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