TRACO Power 8:1 Ultra-Wide Input Non-Isolated POL Converters

TRACO Power’s TSR 1WI and TSR 0.6WI series of non-isolated PoL converters are high-efficiency drop-in replacements for inefficient, legacy LM-type linear regulators. 

The TSR 1WI and TSR 0.6WI have an ultra-wide 8:1 input range covering 9VDC to 72VDC. They can output up to 1A or 0.6A respectively, with a fixed voltage ranging from 3.3VDC to 24VDC. They’re also highly efficient, with efficiency as high as 94%, and have very low standby current.

The high efficiency also reduces heat generation and eliminates the need for a heatsink. The converters can operate at up to 85°C, and the 0.6A converters can operate at full load up to 80°C.
