The PWS725A and PWS726A convert a single 7 to18VDC input to bipolar voltages of the same value asthe input voltage. The converters are capable ofproviding ±15mA at rated voltage accuracy and up to±40mA without damage. (See Output Current Rating.)The PWS725A and PWS726A converters providereliable, engineered solutions where isolated power isrequired in critical applications. The high isolationvoltage rating is achieved through use of a speciallydesignedtransformer and physical spacing. An additionalhigh dielectric-strength, low leakage transformercoating increases the isolation rating of the PWS726A.Reliability and performance are designed in. Thebifilar wound, wirebonded transformer simultaneouslyprovides lower output ripple than competing designs,and a higher performance/cost ratio. The soft-startoscillator/driver design assures full operation of the oscillator before either MOSFET driver turns on,protects the switches, and eliminates high inrush currentsduring turn-on. Input current sensing protectsboth the converter and the load from possible thermaldamage during a fault condition.Special design features make these convertersespecially easy to apply. The compact size allowsdense circuit layout while maintaining critical isolationrequirements. The Input Sync connection allowsfrequency synchronization of multiple converters. TheOutput Sync is available to synchronize ISO120 andISO121 isolation amplifiers. The Enable input allowscontrol over output power in instances whereshutdown is desired to conserve power, such as inbattery-powered equipment, or where sequencing ofpower turn-on/turn-off is desired.
