TSR 3-24150A

Non-Isolated DC/DC Converter (POL) • High performance 3 Amp. switching regulator • Suitable for positive & negative output circuit • • • High efficiency up to 95 % • • • • Short circuit protection Adjustable output voltages Wide input voltage ranges 2.5–5.5, 4.5–14 and 10–30 VDC Remote On/Off input Low output ripple & noise 3-year product warranty TSR 3 Series, 3 A The TSR 3 models are non isolated step down switching regulators. Since production May 2013 they can also be operated with negative output voltage. They come in a very compact open frame package of 15.5 x 9.4 x 6.2mm. The high efficiency of up to 95% admits a full load operation up to 50°C and up to 85°C with 50% current reduction. A low standby current, a very wider input range and no requirement for heatsink give these switching regulators a significant advantage over linear regulators. Togther with a remote On/Off input and protection against short circuit the TSR 3 Series models are ideal point of load regulators for high reliable and energy critical applications.
