Product overview
DK124 is a sub-side feedback type AC-DC switching power supply control chip. The chip adopts highly integrated CMOS circuit design, with output short circuit, secondary open circuit, over temperature, over voltage and other protection functions. The chip has built-in high-voltage power tube and self-powered line, with few peripheral components, simple transformer design (the transformer that isolates the output circuit only needs two windings) and other characteristics.

4KV ESD test
Built-in buffeting function, automatically reduce the working frequency when standby, to meet the European green energy standard (< 0.3W), while reducing the output voltage ripple
Built-in slope compensation circuit to ensure the circuit stability at low voltage and high power output
Frequency jitter reduces EMI filtering costs
Over temperature, over current, over voltage and output short circuit, secondary open circuit protection
Application
Power adapter
LED power supply
induction cooker
Air conditioners, DVDS, set-top boxes and other home appliances
