12、, D3 and D4 and generates an output at 300VDC. This 300VDC fed to T1 (pin2, pin4) which connects to TEA1523P(pin2), then TEA1523P will automatically generate a 50KHz square waveform, this 50KHz square waveform controls the ON/OFF between TEA1523P pin2 and the ground. In normal condition, T1 primary

13、(between pin2 and pin4) will create a 50KHz square waveform which is controlled by TEA1523P, this signal then fed to T1 and generates 2 different potential voltages of 12V and 5V between pin17, pin14 and pin16, pin14 respectively. The 12VDC and 5VDC then rectified by D7, D8, D9 and then filtered by

14、L3, L4, L5, C9, C10 and C11. The feedback voltage is controlled by Ic3 TL431 and IC2 PC817. When the output voltage is higher than 5V, the voltage at TL431(2.5V) is compared with R10 and send out a signal to 5L0380R, the output square waveform then will change to adjust the output voltage, this acts
