ON Semiconductor NCP1351BPG Product Overview

The NCP1351BPG is a sophisticated PWM controller from ON Semiconductor, designed to fulfill the demanding requirements of modern switch-mode power supplies (SMPS). This product is part of the NCP1351 series, which is well-regarded for its high efficiency and reliability in power conversion applications. The NCP1351BPG is particularly suitable for low-power applications, such as standby power systems, auxiliary power supplies, and other compact power solutions.

Key Features

• Current Mode Operation: The NCP1351BPG operates in current mode, which provides superior transient response and simplifies loop compensation.
• Frequency Foldback: To enhance efficiency at light loads, the controller reduces its switching frequency, thereby minimizing switching losses and improving overall efficiency.
• Dynamic Self-Supply: This feature eliminates the need for an auxiliary winding or an external bias supply, which can simplify design and reduce component count.
• Auto-Recovery Overcurrent Protection: The device incorporates an overcurrent protection mechanism that automatically recovers, ensuring the power supply resumes normal operation after a fault condition is cleared.
• Low Standby Power: The NCP1351BPG is optimized for low standby power, making it an excellent choice for applications where energy conservation is critical.
• High-Voltage Startup: This integrated circuit includes a high-voltage startup circuit, which allows for a quick and efficient power-up sequence directly from the high-voltage rail.
