TRACO POWER TSR0.5-2425

DC/DC Converters TSR 0.5 Series, 0.5 A Switching Regulator Features ◆ 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 regu- lators 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 aircooling. Excellent output voltage accuracy and low standby current are other features that- distinguish switching regulators from linear regulators.
