DESCRIPTION
The PWS745 is a set of components useful in the
construction of single or multi-channel isolated
DC/DC converters. By themselves, or in combination
with the PWS740 and PWS750 families of compo-
nents, they allow compact, optimal, and low-cost so-
lutions to many power supply problems.
The PWS745-1 DIP oscillator/driver can be used to
drive up to eight channels of independently isolated
power. The switching MOSFETs are built into the
driver to allow simple low-cost assembly of the multi-
channel converter. The PWS745-1 also is capable of
operating at 5VDC and can be easily synchronized
with TTL level signals. While offering the user an
alternative to the TO-3 package of the PWS740, the
PWS745-1 also allows the user to select varying levels
of power, isolation voltage, mounting technology and
system configuration by choosing among the several
component families. For example, the PWS745-1 can
directly drive the PWS740, PWS745, or PWS750
transformers. It also can drive the FETs of a PWS750
distributed power system. The operating frequency is
compatible with the ISO120 family of isolation ampli-
fiers and is capable of multi-channel synchronized
operation to eliminate troublesome beat frequencies.
The PWS745-2 is a 15V to
±
15V output version, while
the PWS745-4 is the 5V to
±
15V output version. The
PWS740-3 high-speed bridge provides a convenient
rectifier for the selected transformer output.
