Non-Isolated DC/DC Converter (POL)
TSRN 1 Series, 1 A
• SIP-package fits existing TO-220
footprint
• Suitable for positive & negative output
circuit
• Pin compatible with LMxx linear
regulators
• Built in filter capacitors
The new TSRN 1 series step-down switching regulators are drop-in replace-
• ment for inefficient 78xx linear regulators. A high efficiency up to 95% allows
Operation temp. range –40°C to +85°C full load operation up to +70°C (+85°C with derating) ambient temperature
• No heat-sink required • Over-temperature & short circuit
without the need of any heat-sink or forced air cooling. The TSRN-1 switching regulators provide other significant features over linear regulators, i.e.
