The KA5M0965Q-TU is a Fairchild Power Switch (FPS) specifically designed for offline switch-mode power supplies (SMPS). It integrates a high-voltage power MOSFET with a current mode PWM controller in a single package, simplifying design and reducing component count.

Applications:

• Power supplies for DVD players.
• Power supplies for set-top boxes.
• Auxiliary power supplies in TVs.
• Adapters for various consumer electronics.

Features:

• Internal Avalanche-Rugged SenseFET: Provides robust protection against voltage spikes and surges.
• Fixed Frequency Operation: Simplifies EMI filtering and reduces noise.
• Over Voltage Protection (OVP): Protects the power supply and connected load from overvoltage conditions.
• Over Load Protection (OLP): Prevents damage from overload conditions.
• Internal Thermal Shutdown Function (TSD): Protects the device from overheating.

Benefits:

• Simplified Power Supply Design: Integration of MOSFET and controller reduces component count and PCB space.
• Increased System Reliability: Built-in protection features enhance system reliability and prevent damage.
• Improved Efficiency: Fixed frequency operation and optimized design contribute to high efficiency.
• Reduced EMI: Fixed frequency operation simplifies EMI filtering requirements.
