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

  • Non-isolated converter for negative output
  • Small size and low profile
  • Pin compatible with LM79xx linear regulators
  • No heatsink required
  • High efficiency up to 96%
  • Operation temp. range –40°C to +85°C
  • Protection against overload, short circuit and over-temperature
  • Fixed switching frequency
  • Wide input range up to –32 VDC
  • Excellent line / load regulation The new TSN 1 series step-down switching regulators are drop-in replacement for inefficient LM79xx linear regulators. A high efficiency up to 96 % allows full load operation up to +70°C (+85°C with derating) ambient temperature with- out the need of any heat-sink or forced air cooling. The TSN 1 switching regula- tors provide other significant features over linear regulators, i.e. better output accuracy (±2 %), lower standby current of ~2 mA and no requirement of exter- nal capacitors. They are suitable for negative output circuits. The high efficiency and low standby power consumption make these regulators an ideal solution for energy sensitive applications.
