KP201C
The KP201C is a high-performance PWM controller designed for offline flyback power supplies. The chip uses current mode control and supports discontinuous and continuous mode operation. The chip supports over-power output, and the over-power time can be set via an external capacitor. During overload, the system operating frequency and CS shutdown threshold increase according to the feedback voltage FB signal; the switching frequency can reach up to 130kHz. It is suitable for applications such as motor drive power supplies that experience short periods of overload. The KP201C incorporates a high-precision 65kHz switching frequency oscillator and includes a spread-spectrum function to optimize EMI performance. During overload, the chip's operating frequency can reach up to 130kHz. The chip operates in green energy-saving mode and hiccup mode to meet Level VI energy efficiency requirements and standby power consumption of less than 75mW. The KP201C integrates comprehensive protection functions, including: VDD undervoltage protection (UVLO), VDD overvoltage protection (OVP), CS OVP protection, cycle-by-cycle current limiting (Turbo stage), general overload protection (OLP), Turbo overload protection (Turbo OLP), internal overtemperature protection, externally adjustable overtemperature protection (OTP), soft start, LEB, VDD clamping, and CS pin open-circuit protection.
