Power Factor Correction (PFC) is an important branch of power management integrated circuits (PMICs). The SCY99102BDR2G is a high efficiency, low noise, and high current PFC integrated circuit for mobile phones and power adapters. It offers an improved power control loop and an advanced protection system in a single integrated circuit.

The SCY99102BDR2G consists of a buck/boost PFC controller, an input filter, a gate driver, and a current sense amplifier. With its improved design, it can provide up to 94% of power conversion efficiency, which is even higher than the standard 83% efficiency rate. It also has adjustable slope compensation, integrated soft-start with smooth transition, and adjustable ripple and noise reduction. This allows it to provide an efficient and stable power supply.

Having an accurate control loop is essential for optimal power conversion, and the SCY99102BDR2G incorporates a high-performance analog platform to help achieve that. It features two low-voltage differential-signal (LVDS) inputs and one open-drain output in order to facilitate communication and control of the power system. It also contains integrated readback and calibration for easy tuning and optimization.

In addition to its power conversion capabilities, the SCY99102BDR2G also offers several levels of protection for both the system and the user. It comes with over-current, over-temperature, and over-voltage protection. This ensures that the circuit is protected from excessive loads and eliminates the risk of unsafe conditions. It also contains numerous other features such as adjustable soft-start, programmable burst-mode, and adjustable over-temperature protection.

Finally, the SCY99102BDR2G is designed to enable a low noise system. It has a low-noise architecture with EMC certification and provides more than 85dBA of output isolation. This helps to reduce unwanted noise and also meets stringent EMC requirements. It also features a brown-out protection that is designed to protect the system from temporary power issues.

The SCY99102BDR2G is a powerful and versatile Power Factor Correction (PFC) integrated circuit for mobile phones and power adapters. With its advanced design and flexible protection system, it can provide a reliable and efficient power supply. Furthermore, its low-noise architecture and EMC compliance mean it will provide a quiet operating environment. This makes it an ideal choice for a wide range of applications.
