Product Data Sheet 1.5 WATT UNREGULATED DC/DC CONVERTERS DC/DC CONVERTER PWR1726A/PWR1726A1 FEATURES • • • • • • • • • • 8000V ISOLATION TEST VOLTAGE NO EXTERNAL PARTS REQUIRED SYNCHRONIZABLE REMOTE ON/OFF LOW-BARRIER CAPACITANCE APPLICATIONS BIOMEDICAL DATA ACQUISITION INDUSTRIAL PROCESS EQUIPMENT DATA ACQUISITION TEST EQUIPMENT PORTABLE EQUIPMENT DESCRIPTION The PWR1726A/PWR1726A1 is a single-channel, dualoutput 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°C and at rated output power. The performance of the PWR1726A/ PWR1726A1 is not derated over its entire specified temperature range of -25°C to +85°C. Synchronization of the PWR1726A/PWR1726A1 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/PWR1726A1 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 7VDC to 16VDC. Each PWR1726A/PWR1726A1 isolation barrier is tested per the method set forth by UL544, VDE750, and CSA C22.2.
