APPLICATIONS
DESCRIPTION
• Measurement
The YF/YFW Series of DC/DC converters perform over an ultra-wide input voltage range (2:1 and 4:1),
providing indefinite short circuit and overvoltage protection. Single, dual, and triple outputs are available.
This design technology provides up to 20 watts of output power in 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.
