Non-Isolated DC/DC Converter (POL)
TSR 1 Series, 1 A
Up to 96% efficiency – No heat-sink
required
Pin compatible with LMxx linear
regulators
SIP-package fits existing TO-220
footprint
Built in filter capacitors
The 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 temp. range –40°C to +85°C operation up to +60°C ambient temperature without the need of any heat-sink
Short circuit protection Wide input operating range
or forced cooling. The TSR 1 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
Excellent line / load regulation Low standby current
and low standby power consumption makes these
regulators an ideal solution for many battery powered applications.
