: Monitors the 24V output and sends a signal back to the PWM controller to adjust the duty cycle, ensuring the voltage remains stable at the rated 1.1A load. Recommended Next Steps
For a 1.1A continuous current on standard 1 oz/ft² copper, use a trace width calculator. A minimum trace width of roughly 0.5 mm to 0.8 mm is recommended for internal or external layers to prevent the traces themselves from heating up.

A external 8MHz or 12MHz crystal oscillator provides the clock signal, stabilized by two 22pF ceramic capacitors tied to ground.
When designing a circuit using the F4901 1.1A 24V schematic, engineers and technicians should consider the following:
Placed in parallel directly after the F4901 fuse. It clamps unexpected high-voltage spikes (ESD or inductive kickback) to ground, momentarily drawing high current to force the F4901 to trip if the surge persists. Decoupling/Filter Capacitor ( C4901cap C sub 4901
