POSITIVE_TO_NEGATIVE_CONVERTER

Published:2009/7/7 4:29:00 Author:May | From:SeekIC

The transformerless dc-dc converter derives a negative supply voltage from a positive. As a bonus, the circuit also generates a clock signal. The negative output voltage tracks the dc-input voltage linearity (a), but its magnitude is about 3 V lower.Application of a 500- Ω load, (b), causes 10% change from the no-load value.
