The TSR 3 series from Tracopower are non isolated step down switching regulators. These DC to DC converters can also be operated with negative output voltage and they come in a very compact open frame package of 15.5mm x 9.4mm x 6.2mm. The high efficiency of up to 95% admits full load operation up to 50°C and up to 85°C with 50% current reduction. A low standby current, very wider input range and no requirement for heatsink give these switching regulators a significant advantage over linear regulators. TSR 3 series feature remote on/off input, short circuit protection and overtemperature protection. These models are ideal point of load regulators for highly reliable applications.
