2-Watt and 3-Watt SIP-8 DC-DC Converters

The TEC 2/3 (WI) are new series of dc-dc converters from Traco Power with the design purpose to improve the prevalent 2- and 3-Watt SIP-8 dc-dc converters (such as Traco's TMR 2/3E) in terms of cost, efficiency and performance.

The latest technology and components enable an increase in efficiency by more than 20%. With the reduction of thermal loss, the operating temperature range can be expanded from -40°C to +90°C.

The converters are fully regulated over 0 – 100% load (no minimum load is required). The low input range is extended from 4.5- to 13.2-Vdc while models are also available with the standard 2:1 input ranges of 9- to 18-Vdc, 18- to 36-Vdc and 36- to 75-Vdc (see TEC 2WI series for 4:1 input ranges).

In addition, compared with the TMR 2/3E series, the functional I/O-isolation system is approved to IEC/EN 60950-1 with a test voltage (60 s) of 1600 Vdc.

Features include:

  • Outstanding performance - less cost
  • High efficiency for low thermal loss
  • Cost optimized
  • Operating temperature range: -40°C to +90°C
  • Remote On/Off
  • Short circuit protection
  • 3-year product warranty
