The NCP1377BD1R2G is a high-performance PWM controller from ON Semiconductor, specifically designed for switch mode power supplies. This component combines a versatile set of features that enable the design of efficient and reliable power supply systems.

Key Features

• Frequency Jittering: Reduces EMI emissions and simplifies the EMI filtering task by spreading the energy across a wider frequency band.
• Adjustable Skip Cycle: Enhances the efficiency at light loads by skipping unnecessary cycles, which significantly reduces the standby power consumption.
• High-Voltage Startup: With an integrated high-voltage startup source, the NCP1377BD1R2G ensures a quick and efficient power-up sequence.
• Auto-Recovery Overcurrent Protection: The built-in overcurrent protection automatically recovers, which helps to prevent damage to the controller and the power supply during overload conditions.
• Soft-Skipping: When reaching low power demand, the controller enters a controlled burst mode to maintain high efficiency and low standby power.
• Dynamic Self-Supply: Eliminates the need for an auxiliary winding or an external bias supply, simplifying the power supply design.

Applications

The NCP1377BD1R2G is suitable for a wide range of applications, particularly those requiring efficient power conversion and a compact form factor. It is ideal for:

• AC/DC Adapters for Notebooks
