DK025G is a highly integrated 650V/800mΩ GaN HEMT quasi-resonant flyback control AC-DC power switch chip. The DK025G detects the voltage (VDS) between the drain and source of the power tube and opens the power tube when the VDS reaches its lowest value, thereby reducing switching losses and improving electromagnetic interference (EMI). DK025G greatly simplifies the design and manufacture of flyback AC-DC converters, especially for products requiring high conversion efficiency and high power density. DK025G has perfect protection functions: output overvoltage protection (OVP), VCC over voltage protection, over temperature protection (OTP), open loop protection, output over current protection (OCP) ，etc.
DK036G is a quasi-resonant flyback control AC-DC power switch chip with a highly integrated 650V/400mΩ GaN HEMT. The DK036G detects the voltage (VDS) between the drain and source of the power tube and opens the power tube when the VDS reaches its lowest value, thereby reducing switching losses and improving electromagnetic interference (EMI). DK036G greatly simplifies the design and manufacture of flyback AC-DC converters, especially for products requiring high conversion efficiency and high power density. DK036G has perfect protection functions: output overvoltage protection (OVP), VCC over voltage protection, over temperature protection (OTP), open loop protection, output over current protection (OCP)，etc.
