Overview
® 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.
A TTL-compatible ENABLE pin provides output shut-down if desired.
A SYNC pin allows synchronization of several PWS740-1s.
The PWS740-2 is a trifilar-wound isolation transformer using a ferrite core and is encapsulated in a plastic...
