KP201E
The KP201E 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 KP201E 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, achieving standby power consumption of less than 75mW. The KP201E integrates comprehensive protection functions, including: VDD undervoltage protection (UVLO), VDD overvoltage protection (OVP), cycle-by-cycle current limiting, short-circuit protection (SCP), overload protection (OLP), overtemperature protection, soft start, VDD clamping, and CS pin open protection.
