Traco 1A Step Down Switching Regulator - TSN-1 Series


The Traco Power TSN 1 Series of step down switching regulators are a replacement for inefficient 79xx linear regulators. This series of DC/DC converters feature a high efficiency up to 96%, which allows full load operation up to +70°C (+85°C with derating) ambient temperature without the need of any heat sink or forced air cooling. The TSN 1 series of switching regulators also features over linear regulators, lower standby current and no requirement of external capacitors. The TSN 1 DC/DC converters are ideal in applications for energy sensitive applications.

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 temperature 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

Low standby current ∼ 2 mA

3-year product warranty
