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.
