GENERAL DESCRIPTION
Included in the 18-Pin dual-in-line package are two error amplifiers, a sawtooth generator, and the necessary control logic to drive two open-collector power transistors. Also included are protective features, such as adjustable dead-time control, thermal shutdown, soft-start control, and double-pulse protection circuitry. These outputs can be used to implement single-ended or push-pull switching regulation of either polarity in transformerless or transformercoupled converters.
