FSCM0565RJX Application Field and Working Principle

PMIC - AC DC Converters, Offline Switchers are electronic products that convert alternating current (AC) power to direct current (DC) power, and then control and step-down the voltage or current levels to serve the required application. In this regard, FSCM0565RJX is a monolithic integrated MCU based PMIC specifically designed to convert AC power to a regulated 12V DC output. It consists of two integrated AC DC switching converters, namely offline PFC and offline constant current/voltage (CC/CV). This IC is used in various applications such as solar power systems, medical devices and industrial power systems.

The FSCM0565RJX has an integrated offline universal AC/DC node switcher which has the ability to convert AC mains power to the required DC voltage. The primary section is responsible for the PFC conversion of AC mains to DC, followed by constant current/voltage (CC/CV) conversion to the desired regulated output voltage. The IC has the capability to detect AC mains input voltage, current and frequency, and also to control the power factor of the AC mains. Additionally, it has integrated over-voltage protection (OVP), line under-voltage protection (LVP) and line over-voltage protection (HVP) for protecting the DC output from overvoltage and under-voltage conditions. It also has an adjustable switching frequency and an efficiency of up to 90%.

The integrated MCU manages the closed loop control of PFC, CV/CC and AC mains detection functions. The MCU also features an additional internal oscillator to ensure that all the other functional blocks can be synchronized with it. It has a power-saving feature that allows the device to enter its low power state as soon as the mains input voltage falls below a pre-set level. It also has an adjustable soft start feature that prevents inrush current during startup.

In conclusion, FSCM0565RJX is an excellent MCU based PMIC specifically designed to convert AC power to a regulated DC output. It has a high efficiency and can support a wide range of input voltages. Its integrated MCU and integrated AC DC switching converters make it an attractive choice for many applications such as solar power systems, medical devices, and industrial power systems.
