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.
