DESCRIPTION

The CAH series of single, dual, and triple output dc/dc converters performs over an ultra-wide input voltage range (4:1),

providing indefinite short-circuit and over-voltage protection. The CAH series design technology allows for up to 40 watts

output power from a 3.0" x 3.0" x 0.55", or 3.6" x 3.0" x 0.55" with baseplate. These current mode control forward converters

are designed for improved transient response and reduced stress on switching components.
