Additional Details

The KA5M0580R operates at a fixed switching frequency. The integrated SenseFET provides efficient power conversion. The built-in soft start function minimizes stress on the power switch during start-up. Pulse-by-pulse current limiting protects the device from overcurrent conditions. The overvoltage protection (OVP) feature shuts down the device if the output voltage exceeds a certain threshold. Overload protection (OLP) safeguards the power supply from excessive load conditions. The thermal shutdown (TSD) function protects the device from overheating. The auto-restart mode automatically restarts the device after a fault condition is cleared. The device is typically available in a TO-220 package. Operating temperature range typically spans from -25°C to +85°C. The integration of the PWM controller and SenseFET makes this device a cost-effective and reliable solution for power supply applications.
