TSR 0.5-2450

Non-Isolated DC/DC Converter (POL) • • • • • • • • TSR 0.5 Series, 0.5 A Compact SIP package Very high efficiency up to 97% Excellent line / load regulation Low standby current Operating temperature range –40 to 90°C Over-temperature protection Short circuit protection 3-year product warranty TSR 0.5 is a series of step-down non-isolated switching regulators in compact SIP package. These converters are an ideal drop-in replacement to LM78 linear regulators when energy efficiency is a parameter of the design. The high efficiency up to 97% allows full load operation up to +80°C (+90°C with 50% load) ambient temperature without the need of forced air cooling. Excellent output voltage accuracy and low standby current are other features that distinguish witching regulators from linear regulators. Models Order Code Output Current max.
