The NCP1236BD65R2G is a cutting-edge PWM controller from ON Semiconductor, designed to deliver high-performance solutions for AC-DC power supplies. This controller is particularly suitable for applications that demand efficient power conversion, such as switch-mode power supplies (SMPS) for consumer electronics, computer peripherals, and telecommunication devices.

Key Features

• Fixed-Frequency Operation: The NCP1236BD65R2G operates at a 65 kHz fixed frequency, providing a stable switching frequency for noise-sensitive applications.
• High-Voltage Startup: This controller includes a high-voltage startup circuit, allowing it to power up directly from the rectified mains voltage, thereby reducing standby power consumption.
• Adjustable Overcurrent Protection: The device offers an adjustable overcurrent protection feature, enabling fine-tuning to protect the power supply and the load from excessive current conditions.
• Skip-Cycle Operation: At light loads, the controller can skip cycles, which significantly improves the efficiency by reducing the switching losses and extending the standby power performance.
• Brown-Out Protection: The NCP1236BD65R2G is equipped with brown-out protection to prevent operation at abnormally low input voltages, which can help to avoid stress on the power supply components.
• Auto-Recovery Fault Protection: The device integrates protections against overvoltage, overload, and short-circuit conditions with an auto-recovery feature to enhance the reliability of the power supply.
