Model: DK935
Application: [Shaver][Mobile Phone][PDA][MP3]
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 compensation circuit. It is designed with highly integrated CMOS circuit, with few external components and simple transformer design. The isolated output circuit transformer needs only two windings.
