Product Overview: NCP1216D65R2G

The NCP1216D65R2G is a cutting-edge PWM Current-Mode Controller designed and manufactured by ON Semiconductor, a leader in the semiconductor industry. This device is particularly suitable for high-performance off-line power supplies that require efficient and reliable operation.

Key Features

• Adjustable Switching Frequency: The NCP1216D65R2G offers an adjustable frequency range up to 65kHz, allowing designers to choose the optimal frequency for their application, balancing efficiency and component size.
• Current-Mode Control: With its current-mode architecture, the NCP1216D65R2G provides excellent output load regulation and a fast transient response, which is critical for maintaining stable operation under varying load conditions.
• Auto-Recovery Overload Protection: The built-in overload protection automatically recovers once the overload condition is removed, ensuring the power supply's longevity and reliability.
• Frequency Foldback: To enhance efficiency at light loads, the device features frequency foldback, which reduces switching losses by decreasing the frequency under low-load conditions.
• Low Startup Current: The NCP1216D65R2G is designed with a low startup current, minimizing the stress on the startup resistor and reducing power dissipation.
• High-Voltage Startup: This controller includes a high-voltage startup circuit that allows the power supply to start up directly from the rectified mains, eliminating the need for an additional standby transformer.
