PWR1726AC www.murata-ps.com 1.5 Watt Unregulated DC/DC Converter DESCRIPTION DESCRIPTION FEATURES The PWR1726AC is a single-channel, bipolar output DC/DC/ ■ 8000v Isolation Test Voltage converter designed for those applications where high-isolation voltage and low-barrier capacitance are critical for system reliability ■ No External Parts Required and integrity. ■ Remote On/Off Calculated mean-time-to-failure (MTTF) is in excess of 100 years at an ambient temperature of +25°C and at rated output ■ Low-Barrier Capacitance power. The performance of the PWR1726AC is not derated over its ■ RoHS Compliant entire specifi ed temperature range of -25°C to +85°C. Synchronization of the PWR1726AC may be accomplished ■ Synchronizable simply by connecting the Sync-In pin of one unit to the Sync-In pin of another unit. Up to 8 converters may be synchronized in this manner. APPLICATIONS The PWR1726AC provides a plus and minus output voltage that is approximately equal to the magnitude of the input voltage. ■ Biomedical Data Acquisition The unit operates over an input voltage range of 7VDC to 16VDC. ■ Industrial Process Equipment Each PWR1726AC isolation barrier is tested per the method set forth by UL544, VDE750, and CSA C22.2. ■ Data Acquisition ■ Test Equipment ■ Portable Equipment ISO9001 CERTIFIED For full details go to www.murata-ps.com/rohs www.murata-ps.com/support TDC_PWR1726AC.F05 Page 1 of 3 PWR1726AC 1.5 Watt Unregulated DC/DC Converter COMMON SPECIFICATIONS Specifi cations typical at T = +25°C, V = 15VDC, I = ±50mA and in free-running mode unless otherwise noted.

The unit may be synchronized to an external clock. Recommended frequency They are not intended to be subject to surface mount processes under any is a minimum of 110kHz and a maximum of 250kHz. The sync signal must be circumstances. a square wave pulse with a peak of 7.5V min to 12V max, the amplitude being referenced to -Vin. The normal wave soldering process can be used with these devices where the device is subjected to a maximum wave temperature of 260°C for a period of no more than 10 seconds. Within this time and temperature range, the integrity of the device’s plastic body will not be compromised and internal temperatures within the converter will not exceed 175°C. Care should be taken to control manual soldering limits identical to that of wave soldering.
