In order to get the desired size of the output voltage, how to adjust the conduction and cut-off time of the MOS tube to get? The The Thanks
Is automatically adjusted by feedback inside, the outside can not be set. See the 3842 manual, Chinese information online a lot.
2, and then remove the current from the MOS tube drain current information through the other port to return to 3843., to ensure that the load under different load conditions, and can be constant power output.
1, set: the output voltage changes, the sampling potentiometer output voltage also followed by the increase, assuming that the voltage is added to the transistor level, then the transistor C / E between the current increase, C-class voltage decreases, this voltage Is fed back to the feedback end of 3843. Can be used to control the internal sawtooth circuit charge and discharge time. Then you can control the width of the square wave. Output control of the square wave information added to the MOS tube gate level, it can
