DESCRIPTION
LED15 single output DC/DC converters provide up to 15 watts of output power in an
industry standard package and footprint. All models feature a wide input range,
comprehensively protected against over-current, over-voltage and input
under-voltage protection conditions, and trimmable output voltage.
