TOP232Y 3 road output switching supply circuit diagram
The TOP232 Y is used as four-terminal device. The efficiency of the power supply is 78%, the peak-crest value of output is 50 mv. Applied a single slab TOP232 Y, the total output of circuitry is 17.05 W. The d.c.inputs in the range of 200~375 V and 220 V/110 V. It needs to connect to rectifier filters, but no need to apply to input voltage doubler which make doubly rectification to 110 V voltage. The design develops soft start of TOP232 and undervoltage protection well, it has strict current limiting characteristic and high switch frequency characteristic, to make the magnetic core EE19 choosen by high - frequency transformer. Besides, TOP232 Y raises the spacing between the high pressure leak extreme and low-pressure port and lets up the electric leakage of pins, therefore power supply can used under worse environment. C1 is a type of d.c high frequency decoupling capacitance, and neglected when Ui is near from waiting source. The measuring resistance R1 could apply in settling the value of voltage UUV. When Rl=3.9MΩ, UUv=IUVRl=50μA×3.9MΩ=195V. When Ui<195 V, the supply will be cut off automaticly until Ui>195V. (View)

CW494 Double-pointed convertor switching regulated power supply circuit diagram
The circuit diagram CW494 is a type of modulator integrated circuit made from of double-pointed convertor, including an error amplifier, reference voltage source, clock oscillator and vein breadth modulator,etc. The transformer T1 is a high - frequency transformer, which can deliver the energy to the burden. The T2 is a type of driving push transformer, which can deliver the two energizing pulses put by CW494 pulse modulator and amplifiered by energizing drive transistor. And the pulses reach the drive and base of switching tube in push-pull converter circuit diagram. After the variation of voltage and rectification of the pulses from samlping resistance by voltage transformer. The samlping resistance sends the pulses to the pulse modulator circuit diagram CW494, and to be the inverting input of error amplifier. Moreover, the switching power tube adopts rapid series F461. In the places of the feedback fo voltage , the input and output are connected directly. When the input, output need to be insulated, it can adopt photocoupler. (View)

Self-control digital inverter power supply circuit diagram:1.2V rising to 9V
It does not require the establishment of a separate power switch or transformation to switches in the table. The circuit has the advantages of low power consumption, stability and reliability, no effect on instrument accuracy and so on. The transformer T in the circuit is E3-type core, to cut off each corner and process to be the mouth shape, L2 is inside while LJ is outside. When the inverter power supply works, the battery current is about 70mA. As shown in the chart: (View)
