The PWS727 is a DC/DC converter which uses minimal PC board space and converts a single input 10 to 18VDC to bipolar voltages of the same value as the input. The PWS728 converts a 4.7 to 6VDC to bipolar voltages three times the value of the input. The converters are capable of providing ±15mA (PWS727) or ±12mA (PWS728) at rated voltage and up to ±30mA.
