DK935
Description
The DK935 is a high performance CC/CV primary-side AC-DC converter chip. With 850V high voltage switch power transistor integrated, it can detect primary side peak current. It operates in primary-side sensing and regulation, so opto-coupler and TL431 could be eliminated. It also integrated primary-side feedback constant current, constant voltage, self-power supply circuit and output cable pensation circuit. It is designed with highly integrated CMOS circuit, with few external ponents and simple transformer design. The isolated output circuit transformer needs only two windings.
