DC/DC Converter TSR 2 Series, 2 A

Models

◆ Ultra compact SIP package

0.55  0.30  0.40 inch

◆ Up to 96 % efﬁciency

– No heat-sink required

◆ Pin compatible with LMxx

linear regulators

◆ Built in ﬁlter capacitors

◆ Operating temperature range

-40°C to +85°C

◆ Excellent line / load regulation

◆ Short circuit protection

◆ 3-year product warranty

The new TSR 2 series step-down switching regulators are drop-in replacement

for inefﬁcient LMxx linear regulators. A high efﬁciency up to 96 % allows full load

operation up to +67°C ambient temperature without the need of any heat-sink

or forced cooling.

The TSR 2 switching regulators provide other signiﬁcant features over linear

regulators, i.e. better output accuracy (±2 %), lower standby current of 2 mA

and no requirement of external capacitors. The high efﬁciency and low standby

power consumption makes these regulators an ideal solution for many battery

powered applications.
