DC/DC Converters
TSR-3 Series, 3 A
Features
◆ High performance 3 Amp. switching regulator
◆ Suitable for positive & negative output circuit
◆ High efficiency up to 95 %
◆ Adjustable output voltages
◆ Wide input voltage ranges 2.5–5.5,
4.5–14 and 10–30 VDC
◆ Over-temperature protection
◆ Short circuit protection
◆ Remote On/Off input
◆ Low output ripple & noise
The TSR 3 models are non isolated step down switching regulators. Since production
◆ 3-year product warranty
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 and over
temperature the TSR 3 Series models are ideal point of load regulators for high reli-
able and energy critical applications.
