KA5L0380RYDTU Integrated Circuit by ON Semiconductor | AC/DC Converter Power Switch, 3A 800V 50kHz

KA5L0380RYDTU | AC/DC Converter Power Switch (3A / 800V / 50kHz)

Description

The KA5L0380RYDTU from ON Semiconductor is part of the Pro product family, specifically designed for off-line SMPS (Switched Mode Power Supplies) with minimal external components. This Smart Power Switch (SPS) integrates a high-voltage power SenseFET with a current-mode PWM controller, significantly reducing total component count and design complexity compared to traditional discrete MOSFET and controller solutions.

It offers enhanced efficiency, reliability, and productivity in compact power supply designs, making it an excellent choice for both flyback and forward converter topologies.
