KP206X
KP206X Offline current mode PWM control power switch integrating high-voltage start-up and constant current functions The KP206X is a high-performance PWM power switch designed for offline flyback power supplies. The chip integrates a general primary-side constant current control technology, supporting discontinuous mode and continuous mode operation, eliminating the need for an additional constant current loop, and is suitable for isolated power supply applications with constant current requirements. In addition, the KP206X also supports constant power applications. The KP206X has a built-in high-precision 65kHz switching frequency oscillator with a frequency dithering function to optimize EMI performance. The chip operates in green energy-saving mode and hiccup mode, and has a high-voltage self-start function that eliminates the need for a start-up resistor, ensuring standby power consumption of less than 50mW. The KP206X integrates comprehensive protection functions, including: VDD undervoltage protection (VDD UVLO), VDD overvoltage protection (VDD OVP), cycle-by-cycle current limiting (OCP), short-circuit protection (SLP), overload protection (OLP), overtemperature protection (OTP), soft start, leading edge blanking (LEB), and VDD clamping.
