DESCRIPTION
HEC50-S single output DC/DC converters provide up to 50 watts of output power
in an industry standard half-brick package and footprint. These units are
specifically designed to meet the power needs of low-voltage silicon. All models
feature a wide input range, trimmable output voltage and a 15A current rating.
