TSR DC/DC Converters

TRACO Power TSR Series are non-isolated step down DC/DC Converters. These POL (point of load) switching regulators have a very high efficiency and are suitable for replacing linear converters. The TSR-1 series has a high efficiency of up to 96% which allows full load operation up to +60ºC without the need for heat sink or forced cooling. Other features which distinguish TSR-1 over linear regulators include better output accuracy (±2%) and lower standby current of 2mA. Additionally, TSR-1 requires no external capacitors. This series is ideal for many battery powered applications. Learn More
