The NCP1340B3D1R2G is a high-performance PWM controller designed by ON Semiconductor, tailored for AC-DC power conversion applications. This component is a critical choice for designers seeking efficient and reliable solutions for power supplies in consumer electronics, computing, and industrial systems.

Key Features

• Quasi-Resonant Operation: The device operates in a quasi-resonant mode, which reduces electromagnetic interference (EMI) and improves efficiency by minimizing switching losses.
• High-Voltage Startup: It includes an integrated high-voltage startup circuit, which enables the controller to quickly begin operation directly from the rectified mains voltage, thereby reducing standby power consumption.
• Frequency Jittering: Frequency jittering helps in spreading the EMI spectrum, further reducing potential interference with other electronic devices.
• Dynamic Self-Supply (DSS): The DSS feature eliminates the need for an auxiliary winding, simplifying the power supply design and reducing overall component count.
• Adjustable Brown-Out Detection: The controller provides a brown-out detection feature that protects the system from operation under hazardous low-line conditions.
• Overcurrent and Overvoltage Protection: Built-in protection mechanisms safeguard the device and the system from damage due to overcurrent and overvoltage conditions.
