DC/DC Converters TSR 0.5SM Series, 0.5 A Switching Regulator Features Compact SMD package Very high efcfi iency up to 97% Excellent line / load regulation Low standby current Operating temperature range 40 to 90C 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 nonisolated switching regulators in compact 3-year product warranty SIP package. These converters are an ideal alternative to LM78 linear regulators when energy efcfi iency is a parameter of the design. The high efcfi iency up to 97 % allows full load operation up to +80C (+90C 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.
