TSR DC/DC Converters

TRACO Power TSR 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 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 over linear regulators include better output accuracy (±2%) and a lower standby current of 2mA. Additionally, TSR requires no external capacitors. This series is ideal for many battery-powered applications.
