Additional Details:

The FP6131-25GS3GTR uses a constant frequency PWM control scheme to regulate the output voltage. It features a built-in soft-start function to limit inrush current during startup. The device also includes a power-good indicator that signals when the output voltage is within the specified regulation range. The over-current protection is implemented using current sensing, and the over-temperature protection is achieved using a thermal shutdown circuit. The device is available in a small QFN package for easy integration into compact designs.
