Non-Isolated DC/DC Converter (POL) TSR 1E Series, 1 A

  • Highly cost efficient design
  • Pin compatible with LMxx linear regulators
  • Operation temperature. range –40°C to +85°C
  • Efficiency up to 92%
  • Wide input operating range 6-36 VDC
  • Short circuit protection
  • Excellent line / load regulation
  • 3-year product warranty The TSR 1E is a 1 Ampere step-down switching regulator series and a drop-in replacement for inefficient 78xx linear regulators. This series comes in a stan- dard plastic SIP-3 case and complements our existing POL portfolio with a se- ries focusing strongly on a cost efficient design while maintaining our quality standards. The effective design allows full load operation up to +60°C ambient temperature without the need of any heat sink or forced cooling. The TSR 1E switching regulators provide other significant features over linear regulators, i.- e. better output accuracy, lower standby current and no requirement of external capacitors. The TSR 1E series offers a broad application range in many envi- ronments and is especially suited for high volume projects where the series will help to reduce production cost by delivering not only a highly cost efficient but also reliable solution.
