TSR1-2450E
Non-Isolated DC/DC Converter (POL)
TSR 1E Series, 1 A
Highly cost efficient design
Pin compatible with LMxx linear
regulators
Operation temperature. range –40°C to
+85°C
Efficiency up to 92%
Wide input operating range 6-36 VDC
Short circuit protection
Excellent line / load regulation
3-year product warranty
The TSR 1E is a 1 Ampere step-down switching regulator series and a drop-in
replacement for inefficient 78xx linear regulators. This series comes in a stan-
dard plastic SIP-3 case and complements our existing POL portfolio with a se-
ries focusing strongly on a cost efficient design while maintaining our quality
standards. The effective design allows full load operation up to +60°C ambient
temperature without the need of any heat sink or forced cooling. The TSR 1E
switching regulators provide other significant features over linear regulators, i.-
e. better output accuracy, lower standby current and no requirement of external
capacitors. The TSR 1E series offers a broad application range in many envi-
ronments and is especially suited for high volume projects where the series will
help to reduce production cost by delivering not only a highly cost efficient but
also reliable solution.
