Working Principle

The FLS3217N is a step-down DC-DC converter with an integrated power PMIC and LED driver. The device utilizes a high-frequency switching topology, which allows for a high efficiency power conversion. The FLS3217N is capable of delivering up to 3A of output current and can also support up to 30V output voltage. The device integrates a power PMIC and LED drivers, allowing for simplified LED lighting systems and reduced BOM cost.At the heart of the device is the integrated power PMIC and LED driver. The power PMIC samples the input voltage and adjusts the switching frequency to maintain a constant output. The LED driver then takes the output from the power PMIC and drives the LED output at a constant voltage, ensuring maximum brightness and efficiency. The FLS3217N also has a built-in ESD protection and a low-noise output transformer, which helps to reduce the system EMI.
