Try the effective replacement for standard 78xx regulators

1A DC/DC switch-mode regulators TRACO TSR-1 already found their stable place on the market and they successfully replace inefficient linear regulators.

This is an archive article published 28.02.2013. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.
Switch-mode power supplies are still more used in all segments of power supply, to which also belongs a regulation on the side of the load (Point Of Load - POL). Perhaps every designer is familiar with classic linear stabilizers of the 78xx or 79xx series. It can be said, that linear stabilizers are still suitable for applications, where there´s not a too high power loss arising on them. But when we need to gain for example a 5V/0,5A from 12V, a power loss of approx. 7V x 0,5A=3,5W is arising on the regulator. That is already a quite considerable power, which requires a sufficiently sized heatsink and a place on a PCB. At nowadays power consumption decreasing trend, it is better preferable to eliminate useless losses, what also enables to produce a device, which is less heating, thus also being usually more reliable.
TSR-1 from company TRACOPOWER represents a pin-compatible replacement for 78xx linear regulators and it also contains input and output filtering capacitors. TSR-1 reaches up to 96% efficiency (80-90% in average) thus not requiring a heatsink. Depending on local conditions in your device, it is only necessary to observe power derating of 2%/°C at temperatures of the regulator above 60°C (if such conditions can occur in your device). TSR-1 also provides further benefits like for example excellent line and load regulation, resistance to a continuous shortcut and an industrial range of operating temperatures.
Available are 10 versions with output voltages from 1,2 to 15VDC. Detailed information will provide you the TSR-1 datasheet. In case, you need to obtain a negative voltage, then the TSRN-1 series is suitable for you.

Advantages / Features:

  • up to 96% efficiency - no heatsink necessary
  • SIP package, pin compatible with 78xx regulators in a TO220 package
  • complete solution including an inductor and capacitors (no external capacitors necessary)
  • operating range from -40°C to +85°C
  • continuous short circuit protection
  • wide input voltage range
  • perfect stability of output voltage (approx 0,6%)
  • output voltage set accuracy +-2%
  • low standby current (2mA)
  • ideal also for battery powered devices
