PWS727 General Description
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. * Use a 10V zener on PWS728 to prevent input spikes overstressing the diode bridge.
The PWS727 and PWS728 use a high-frequency (800kHz nominal) surface mount oscillator that makes it possible to minimize the transformer size. The transformer is composed of a split bobbin isolation transformer using a ferrite core and is encapsulated in a plastic package, allowing a higher isolation voltage rating. The design minimizes high frequency radiated noise on the output by using a ground plane directly under the high frequency components.
