The NCP1399AIDR2G is a high-performance, high-efficiency resonant mode controller designed by ON Semiconductor to cater to the demanding needs of modern switch mode power supplies (SMPS). This versatile component is an excellent choice for applications such as LCD and PDP TVs, desktop monitors, and any other power supply that requires a low-profile form factor and high efficiency.

Key Features

• Resonant Mode Operation: The NCP1399AIDR2G operates in a resonant mode, which allows for zero voltage switching (ZVS) or reduced voltage switching, thereby minimizing switching losses and enhancing overall efficiency.
• Adjustable Operating Frequency: It includes an adjustable frequency range that can be set through external components, offering designers the flexibility to optimize the performance for their specific applications.
• High-Voltage Startup: An integrated high-voltage startup circuit ensures reliable startup and reduces the number of external components required, simplifying the design and reducing the bill of materials.
• Brown-Out Detection: The controller features brown-out detection, which protects the power supply during conditions of low input voltage, ensuring stable operation under adverse conditions.
• Overcurrent and Overvoltage Protection: Comprehensive protection features including overcurrent, overvoltage, and short-circuit protection safeguard the power supply and the end application from various fault conditions.
• Auto-Recovery Mode: In the event of a fault condition, the NCP1399AIDR2G automatically enters a safe burst mode, which helps to prevent component damage and allows for auto-recovery once the fault condition is cleared.

Applications

The NCP1399AIDR2G is suitable for a wide range of power supply designs, particularly where high efficiency and compact size are critical. Its application areas include but are not limited to:

• Flat-panel televisions and monitors
• Networking power supplies
• Adapters for notebooks and gaming consoles
• Server and telecom power supplies

Package and Availability

The NCP1399AIDR2G is available in a compact SOIC-16 package, allowing for a small footprint on the PCB. ON Semiconductor's commitment to quality ensures that each device meets the highest standards of performance and reliability.
