<p>The feedback current controls the charging amount of a capacitor (C3) that controls the on-time of a transistor (Q1) of the primary side, and which controls the charging amount of a speed-up capacitor (C2) of the primary side. The charging amount of the capacitor (C3) that controls on-time and the charging amount of the speed-up capacitor (C2) on the primary side are regulated in order to narrow the on time of the transistor (Q1) of the primary side.</p> |
