+5V, 1A DC output flyback switching power supply circuit TOP100Y

  
TOP100Y constituted by a + 5v, 1A output flyback DC switching power supply circuit is shown. This flyback
+5V, 1A DC output flyback switching power supply circuit TOP100Y - schematic

switching power supply output voltage is directly regulated by a feedback circuit for applications requiring isolation and load change is small. When the DC input voltage Ui = 95 ~ 185V, the voltage regulation Sv = 1.25%. When the load current changes from l0% to l00%, the load regulation SI = 4.5%. The output ripple voltage is 25mV. Switching frequency is still 100kHz (typ).Clamp circuit consists of transient voltage suppression diodes VDz (P6KE91) and ultra-fast recovery diode VDl (UF4004) components. Secondary voltage VD3, C2, L, C3 after rectifier filter to obtain a + 5V output. After the adoption of the feedback coil voltage VD2, R and Cl rectifier filter, applied to the control terminal of TOPl00Y. Cl doubles as a control loop compensation capacitor, and decided to auto-restart frequency.
