KP201F
KP201F Offline Current Mode PWM Controller Supporting Multiple Output Modes The KP201F is a high-performance PWM controller designed for offline flyback power supplies. The chip integrates a universal primary-side constant current control technology, supporting discontinuous mode and continuous mode operation, suitable for isolated power supply applications with constant current output. The chip supports constant power output and is suitable for motor drive power supplies, etc. The KP201F has a built-in high-precision 65kHz switching frequency oscillator and features frequency dithering to optimize EMI performance. The chip operates in green energy-saving mode and hiccup mode, achieving standby power consumption of less than 75mW. The KP201F integrates comprehensive protection functions, including: VDD undervoltage protection (UVLO), VDD overvoltage protection (OVP), cycle-by-cycle current limiting, output short-circuit protection (CS_UVP), output overvoltage protection (CS_OVP), overtemperature protection, soft start, VDD clamping, and CS pin open-circuit protection, etc.
