Embodiment Construction

[0007] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0008] The module of the present invention is integrally packaged in an aluminum shell, and is composed of an integrated circuit IC (SG3842), a field effect transistor GZ, resistors R1-R10, a transformer B, a diode D and capacitors C1-C4. The secondary pole of the transformer B passes through the diode D and then connects the voltage dividing resistors R2, R3, and R4 in series. One end of R2 is connected to the pin 7 of the integrated circuit IC, and connected to the drain of the field effect transistor GZ after being connected to R1, and the other end is connected to the resistor R8 in parallel with the capacitor C3. The branch is then connected to IC pin 1 of the integrated circuit, the central contact of the potentiometer is connected to the contact of R2, the parallel branch of resistor R8 and capacitor C3, and connected to IC pin 2 of the integrated circuit, the ...

Description

technical field [0001] The invention relates to a switching power supply module. Background technique [0002] The early switching power supply was not easy to repair if it was damaged. Because the power supply is broken, the TV does not work, and the corner voltage is abnormal, so it is difficult to repair. Because of its long-term work under high voltage, the power supply is a vulnerable product. There is an existing power supply board, which can be equipped with a power supply part, but there are many disadvantages, such as large volume, many connections, few suitable models, and because there are too many leads, the power frequency is prone to radiation, which affects itself and other TV effects. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects in the prior art and provide a switching power supply module with good heat dissipation, shielding effect and no radiation. [0004] The invention is realized t...
