The TSR 1 series from Tracopower are non isolated step down switching regulators in SIP package. These DC to DC converters are drop-in replacement for inefficient 78xx linear regulators. A high efficiency up to 96% allows full load operation up to 60°C ambient temperature without need of any heat sink or forced cooling. The TSR 1 switching regulators provide many significant features over linear regulators, such as better output accuracy (±2%), lower standby current of 2mA 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.


  • Output voltage range from 1.2VDC to 15VDC
  • Maximum output current is 1A
  • Switching frequency is 500KHz
  • Pin compatible with LMxx linear regulators
  • SIP package fits existing TO-220 footprint
  • Built-in filter capacitors
  • Operation temperature range from -40°C to 85°C
  • Short circuit protection
  • Wide input operating range from 4.6VDC to 36VDC
  • Excellent line and load regulation

The specs are:
Output Current: 1A
Output Voltage: 12V
Power Rating: 1W

Does this mean I can power a 7Watt device with this power converter? What is the 1W? Is that the power consumed (makes sense as the device is ~92% efficient)?

According to the specification this part has

Output Voltage = 12VDC
Output Current = 1A

power rating P=V*I comes to 12 Watts so you can take 7 watts output power, its efficiency is around 95%, for more information please refer below linked datasheet
