DESCRIPTION
The PWR1726A is a single-channel, dual-output DC/DC
converter designed for those applications where high-
isolation voltage and low-barrier capacitance are critical for
system reliability and integrity.
Calculated mean-time-to-failure (MTTF) is in excess of
100 years at an ambient temperature of +25擄C and at rated
output power. The performance of the PWR1726A is not
derated over its entire specified temperature range of -
25擄C to +85擄C.
Synchronization of the PWR1726A may be accomplished
simply by connecting the sync pin of one unit to the sync
pin of another unit. In this manner, up to eight converters
may be ganged together.
The PWR1726A provides a plus and minus output voltage
that is approximately equal to the magnitude of the input
voltage. The unit operates over an input voltage range of
7V
DC
to 18V
DC
.
Each PWR1726A isolation barrier is tested per the method
set forth by UL544, VDE750, and CSA C22.2.
