14+ Uc3842 Power Supply Schematic. Uc3842 ic can be easily found in most of the electronic equipment switching power supply. Ka3842/43/44/45 are fixed frequency current mode pwm. They are specially designed for off−line and dc to dc converter applications with a input voltage open loop voltage gain power supply rejection ratio output sink current output source current high output voltage low output. Based on uc3842 pwm control technology, this paper designs the switching power supply with figure 1.
