F4901 1.1a 24v Schematic

When Q1 turns OFF, the magnetic field collapses. The secondary winding of T1 releases energy through D1 (Schottky diode) into output capacitor C3. The output voltage rises toward 24V.

Before diving into the schematic, we must identify the component labeled "F4901." f4901 1.1a 24v schematic
