The TSR 3-2450 is a non-isolated step-down PoL Switching Regulator, can also be operated with negative output voltage. The high efficiency of up to 95% admits a full load operation up to 50 and up to 85°C with 50% current reduction. A low standby current, a very wider input range and no requirement for heat-sink give these switching regulators a significant advantage over linear regulators. Together with a remote on/off input and protection against short-circuit and over-temperature the TSR 3 series models are ideal point of load regulators for high reliable and energy critical applications.
