TRACO POWER TSR0.5-2425SM

DC/DC Converters TSR 0.5SM Series, 0.5 A Switching Regulator Features ◆ Compact SMD package ◆ Very high efficiency up to 97% ◆ Excellent line / load regulation ◆ Low standby current ◆ Operating temperature range –40 to 90°C ◆ Over-temperature protection ◆ Remote On/Off input ◆ Adjustable output voltage ◆ Short circuit protection ◆ Moisture sensitivity level 2 as per IPC J-STD-020D.1 TSR-0.5SM is a series of step-down non–isolated switching regulators in compact ◆ 3-year product warranty SIP package. These converters are an ideal alternative 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 aircooling. Excellent output voltage accuracy and low standby current are other features that- distinguish switching regulators from linear regulators.
