The ML4815CP is an integrated circuit (IC) component designed for power factor correction (PFC) applications. It provides a range of features that enable efficient and reliable power conversion. Here are some key features and an overview of this IC component:
1. PFC Controller: The ML4815CP serves as a PFC controller, which means it regulates the input current to follow the shape of the input voltage waveform closely. This achieves a high power factor, which reduces energy consumption and improves the efficiency of the power supply.
2. Boost Converter: The IC operates as a boost converter, controlling the output voltage to be higher than the input voltage. It uses a Continuous Conduction Mode (CCM) to regulate the output voltage accurately.
3. Universal Input Range: The ML4815CP is designed to work with a wide universal input voltage range, typically 85 VAC to 265 VAC. This makes it suitable for various applications and regions, accommodating different mains voltages.
4. High Voltage Start-Up: The IC features an internal high voltage start-up circuitry, enabling it to directly start from the rectified mains voltage without requiring an additional circuit or manual intervention. This simplifies the design and reduces component count.
5. Current Limiting: It incorporates a current limit functionality that protects the power supply against overloading and short circuits. This prevents damage to the components and ensures the safety and longevity of the power supply
