The TUHS3F05 from Cosel is an Isolated AC-DC Converter that steps down an AC input voltage of 85 - 264 V to a DC output voltage of 5 V. It also accepts a DC input voltage of 120 - 370 V. This AC-DC converter delivers an output power of 3 W and has an efficiency of 79%. It utilizes synchronous rectification technology and offers high efficiency while maintaining a low standby power. This UL60950-1-flame retardant converter provides design flexibility for hold-up time and expected life. It requires an external capacitor to select the input value. This RoHS-compliant converter has built-in over-current protection (OCP) and over-voltage protection (OVP) to prevent over-load-related damages. It is available in a PCB-mount package that measures 28.7 x 12.7 x 17.5 mm and is ideal for commercial applications.
