KP226X
KP226X High-voltage startup, offline current mode PWM control power switch KP226X is a high-performance power switch designed for offline flyback power supplies. Its integrated high-voltage startup circuit improves system startup time and effectively reduces standby power consumption. KP226X has a built-in high-precision 65kHz switching frequency oscillator and a spread-spectrum function to optimize EMI performance. The chip operates in green energy-saving mode and hiccup mode, and has a high-voltage self-startup function that eliminates the need for a startup resistor, ensuring standby power consumption of less than 50mW. KP226X integrates complete protection functions, including: VDD undervoltage protection (UVLO), VDD overvoltage protection (OVP), cycle-by-cycle current limit (OCP), overload protection (OLP), overtemperature protection (OTP), soft start, and VDD clamping.
