DC/DC Converters

TSR-1 Series, 1 A

Features

◆ Up to 96 % efﬁciency

–> No heat-sink required

◆ Pin compatible with LMxx linear regulators

◆ SIP-package ﬁtsexisting TO-220 footprint

◆ Built in ﬁlter capacitors

◆ Operation temp. range –40 to +85 °C

◆ Short circuit protection

◆ Wide input operating range

◆ Excellent line / load regulation

◆ Low standby current

◆ 3-year product warranty

The new TSR-1 series step-down switching regulators are drop-in replacement for

inefﬁcient 78xx linear regulators. A high efﬁciency up to 96 % allows full load

operation up to +60 °C ambient temperature without the need of any heat-sink or

forced cooling.

The TSR-1 switching regulators provide other signiﬁcant features over linear regu-

lators, 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.
