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.

NOTES
1. All case and pin dimensions reference only unless otherwise noted.
2. Baseplate protrudes 0.02”, two sides.
3. PC pins 0.04” dia x 0.18” long minimum: typical nine places.
4. Pin-to-pin tolerance ±0.01”. Pin dimension tolerance ±0.005”.
5. 10% minimum load required on outputs.
Singles: ±1% min. to full load
Duals: ±1% min. to full load (balanced)
±5% min. to max load (unbalanced)
Triples: ±1% min. to full load (main output)
±5% min to full load aux (unbalanced)
6. Significant capacitive load may inhibit start-up and operation, consult factory.
7. Ripple & Noise is measured with a 0.1μF capacitor across the output.
