PWS740 - Distributed Multi-Channel Isolated DC-TO-DC CONVERTER

Download the PWS740 datasheet PDF. This datasheet also covers the PWS740_Burr variant, as both devices belong to the same distributed multi-channel isolated dc-to-dc converter family and are provided as variant models within a single manufacturer datasheet.

Description

The PWS740 is a multichannel, isolated DC-to-DC converter with a 1500VAC continuous isolation rating.

The outputs track the input voltage to the converter over the range of 7 to 20VDC.

® PW S74 0 PWS740 Distributed Multi-Channel Isolated DC-TO-DC CONVERTER FEATURES ISOLATED ±7 TO ±20VDC OUTPUTS BARRIER 100% TESTED AT 1500VAC, 60Hz LOWEST POSSIBLE COST PER CHANNEL MINIMUM PC BOARD SPACE 80% EFFICIENCY (8 CHANNELS, RATED LOADS) q FLEXIBLE USE WITH PWS745 COMPONENTS q q q q q APPLICATIONS q INDUSTRIAL MEASUREMENT AND CONTROL q DATA ACQUISITION SYSTEMS q TEST EQUIPMENT The PWS740-1 is a high-frequency (400kHz nominal) oscillator/driver, handling up to eight channels. This part is a hybrid containing an oscillator and two power FETs. It is supplied in a TO-3 case to provide the power dissipation necessary at full load. Transformer impedance limits the maximum input current to about 700mA at 15V input, well within the unit’s thermal limits.
