The NCP1203D100R2G is an integrated circuit (IC) component manufactured by ON Semiconductor. It is a switching converter designed for use in switch mode power supplies (SMPS) and is specifically optimized for low power applications. This IC is widely used in various electronic devices, including LED drivers, adapters, and battery chargers. Here, we will provide an overview of the NCP1203D100R2G and highlight its key features.
The NCP1203D100R2G is a fixed-frequency current-mode controller capable of operating in both continuous and discontinuous conduction modes. It offers a number of features that make it suitable for low power applications. Firstly, it has a built-in 70 kHz oscillator, allowing for better efficiency and precise control of the switching frequency. The IC also incorporates external synchronization capability, enabling it to sync with an external clock if required.
To ensure reliable power management, the NCP1203D100R2G offers protection features such as thermal shutdown and overvoltage protection. The thermal shutdown feature helps prevent the IC from overheating by shutting down the device when the internal temperature exceeds the specified threshold. Similarly, the overvoltage protection feature safeguards the circuit by shutting down the power supply when the output voltage exceeds a certain limit.
Furthermore, this IC component includes a soft-start function to minimize inrush current during startup
