The LM3489MM is an integrated circuit (IC) component designed for step-up and flyback DC-DC conversion applications. It is manufactured by Texas Instruments and is widely used in various power supply designs. This IC has several key features that make it a popular choice for power management applications.
One of the notable features of the LM3489MM is its capability to operate from a wide input voltage range of 4.5V to 30V, making it suitable for different power sources. It can also handle an output voltage range of up to 35V, providing flexibility in generating higher voltage levels.
The LM3489MM offers a programmable operating frequency ranging from 100 kHz to 1 MHz, allowing designers to optimize the performance based on their specific requirements. This adjustable frequency feature helps in minimizing the size of external components while providing efficient power conversion.
To ensure enhanced energy efficiency, the LM3489MM employs an adjustable slope compensation technique, which significantly improves the transient response and stability of the power supply. This allows for a more reliable and regulated output voltage, even under varying load conditions.
Another key feature of the LM3489MM is its ability to provide both constant voltage (CV) and constant current (CC) regulation modes. This feature makes it suitable for various applications such as battery charging, enabling the IC to regulate the charging current to maintain a constant level without exceeding the specified maximum
