The NCP1248AD100R2G is an integrated circuit (IC) component designed for power management applications in switch-mode power supplies (SMPS). It belongs to ON Semiconductor's NCP1248 series of controllers that offer high performance and efficiency.
This IC features a current mode control technique, which enables stable and reliable operation of the power supply. It operates with a wide input voltage range, making it suitable for various power supply designs.
One of the key features of the NCP1248AD100R2G is its built-in protection mechanisms. It incorporates features like overcurrent protection (OCP), which safeguards the power supply and connected devices from excessive currents. The Overtemperature Protection (OTP) prevents the IC from overheating, ensuring its longevity and reliability.
Another notable feature is that it supports skip mode operation, which helps improve power efficiency during light-load conditions. This allows the power supply to maintain high efficiency even when the load is reduced, resulting in energy savings.
The NCP1248AD100R2G also includes a programmable soft-start feature, which enables a controlled and smooth power-up sequence. This feature prevents excessive inrush currents during startup, thereby increasing the reliability of the power supply.
In terms of the package, it is available in a compact DFN-8 (3x3 mm) package, which offers a space-saving solution for compact power supply designs. This package type also enables easy and efficient assembly onto PCBs (printed circuit boards)
