Non-Isolated DC/DC Converter (POL) TSR 0.5 Series, 0.5 A

  • Compact SIP package
  • Very high efficiency up to 97%
  • Excellent line / load regulation
  • Low standby current
  • Operating temperature range –40 to 90°C
  • Over-temperature protection
  • Short circuit protection
  • 3-year product warranty TSR 0.5 is a series of step-down non-isolated switching regulators in compact SIP package. These converters are an ideal drop-in replacement to LM78 linear regulators when energy efficiency is a parameter of the design. The high effi- ciency up to 97% allows full load operation up to +80°C (+90°C with 50% load) ambient temperature without the need of forced air cooling. Excellent output voltage accuracy and low standby current are other features that distinguish witching regulators from linear regulators.
