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 speciallydesigned
transformer and physical spacing. An additional 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 oscillator before either MOSFET driver turns on,
protects the switches, and eliminates high inrush currents 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 isolation 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.
