Overview

The KB7800-500 series represents a new generation of high-efficiency switching regulators, serving as an ideal replacement for the traditional LM78xx series of linear three-terminal voltage regulators. With efficiency reaching up to 96%, minimal energy is wasted, resulting in low heat generation—eliminating the need for heat sinks, along with their associated space requirements and costs. This series supports negative output and is widely utilized in industrial control, instrumentation, and power electronics applications.
