ON Semiconductor NCP1013AP100 Self-Supplied Monolithic Switcher for Low Standby-Power Offline SMPS

The ON Semiconductor NCP1013AP100 is a highly integrated, self-contained power switching solution designed to offer efficient power conversion with minimal standby power consumption. This product is part of ON Semiconductor's NCP1013 series, which is known for its robust performance in low-power offline switched-mode power supplies (SMPS).

Key Features

• Integrated High-Voltage Switch: The NCP1013AP100 incorporates a high-voltage MOSFET with a typical breakdown voltage of 700V, providing a reliable switching mechanism for enhanced power handling capability.
• Fixed-Frequency Operation: The device operates at a fixed frequency of 100 kHz, which simplifies the design of the power supply and helps in noise reduction.
• Self-Supply Capability: The absence of an auxiliary winding reduces the complexity of the power supply design, as the NCP1013AP100 derives its operating power directly from the high-voltage rail.
• Current-Mode Control: The current-mode control provides inherent input voltage feed-forward compensation and cycle-by-cycle current limiting which enhances the overall system reliability and performance.
• Low Standby Power: Designed with energy efficiency in mind, the NCP1013AP100 features a very low no-load standby power consumption, making it suitable for applications where energy conservation is critical.
• Frequency Jittering: Reduces EMI emissions and eliminates the need for additional EMI filtering components, simplifying the design and reducing the overall cost.
• Overpower and Overvoltage Protection: The device includes built-in protection features that safeguard the power supply and the load against various fault conditions.

Applications

The NCP1013AP100 is ideal for a wide range of applications where efficient power conversion and low standby power are essential. It is particularly well-suited for:

• AC-DC adapters for cell phones, PDAs, and other portable devices
• Standby and auxiliary power supplies for green-mode power supplies
• Small home appliances and office equipment
• Industrial power supplies with lower power requirements

Overall, the ON Semiconductor NCP1013AP100 is a versatile and energy-efficient solution for designers looking to optimize their power supply designs for performance, reliability, and cost-effectiveness.
