Product Information

www.DataSheet4U.com YF SERIES UP TO 20 WATTS - YF SERIES ULTRA-WIDE INPUT, LOW QUIESCENT CURRENT TO 20 WATTS FEATURES • • • • • • • • Single, Dual and Triple Outputs Industry Standard Package and Pin-Out Pi Input Filter Integral to Converter 1600VDC I/O Isolation Regulated Output Continuous short circuit protection Remote On/Off Feature UL1950, cUL950, EN60950 and CE MARK THE YF SERIES FROM WALL INDUSTRIES The YF series of DC/DC converters performs over an ultra-wide input voltage range (2:1 & 4:1), providing indefinite short circuit and overvoltage protection. The series’ design technology allows up to 20 watts of output power from a 1.60” x 2.0” x 0.40” case. These current mode control forward converters are designed for improved transient response and reduced stress on switching components and do not require external input filtering, making it a preferred source over industry alternatives.
