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.

1) input voltage must be at least 0.5 V higher than output voltage

2) input voltage must be at least 2.0 V higher than output voltage, max. 9 VDC if output is <0.9 VDC

3) input voltage must be at least 3.0 V higher than output voltage

4) max. input voltage = 14-|Vout|

5) max. input voltage = 30-|Vout|

6) open trim input = min. output voltage
