SYNCHRONIZATION SIGNAL FOR USE
WITH ISO120 AND ISO121
oscillator before either MOSFET driver turns on,
protects the switches, and eliminates high inrush cur-
rents during turn-on. Input current sensing protects
both the converter and the load from possible thermal
damage during a fault condition.
Special design features make these converters
especially easy to apply. The compact size allows
dense circuit layout while maintaining critical isola-
tion requirements. The Input Sync connection allows
frequency synchronization of multiple converters. The
Output Sync is available to synchronize ISO120 and
ISO121 isolation amplifiers. The Enable input allows
control over output power in instances where
shutdown is desired to conserve power, such as in
battery-powered equipment, or where sequencing of
power turn-on/turn-off is desired.
DESCRIPTION
The PWS725A and PWS726A convert a single 7 to
18VDC input to bipolar voltages of the same value as
the input voltage. The converters are capable of
providing
±
15mA at rated voltage accuracy and up to
±
40mA without damage. (See Output Current Rating.)
The PWS725A and PWS726A converters provide
reliable, engineered solutions where isolated power is
required in critical applications. The high isolation
voltage rating is achieved through use of a specially-
designed transformer and physical spacing. An addi-
tional high dielectric-strength, low leakage transformer
coating increases the isolation rating of the PWS726A.
Reliability and performance are designed in. The
bifilar wound, wirebonded transformer simultaneously
provides lower output ripple than competing designs,
and a higher performance/cost ratio. The soft-start
oscillator/driver design assures full operation of the
