DC/DC Converter
TSR 2 Series, 2 A
◆ Ultra compact SIP package
0.55 x 0.30 x 0.40 inch
◆ Up to 96 % efficiency
– No heat-sink required
◆ Pin compatible with LMꢀꢀ
linear regulators
◆ Built in filter capacitors
◆ Operating temperature range
-40°C to +85°C
◆ Eꢀcellent 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.
