KA5Q1265RF Description

Short technical summary and product information.

The KA5Q1265RF by On Semiconductor is a Fairchild Power Switch (FPS) specifically designed for implementing off-line switch mode power supplies (SMPS) for color televisions. This component integrates a high-voltage SenseFET and a current-mode PWM controller IC, reducing the need for external components and leading to smaller, more efficient designs.

 

The KA5Q-series utilizes a Quasi Resonant technique, incorporating a capacitor between the MOSFET drain and source to minimize switching noise (EMI). It also features burst mode operation for reduced power consumption during standby.

 

This product family enables cost-effective designs for color television power supplies. The KA5Q1265RF is available in TO-220F and TO-3PF packages, suitable for various mounting requirements.
