KP201A
KP201A External Over-temperature/Over-voltage Protection, Offline Current Mode PWM Controller The KP201A is a high-performance PWM controller designed for offline flyback power supplies. The chip uses current mode control and supports discontinuous mode and continuous mode operation, suitable for isolated power supply applications with constant voltage output. The KP201A has a built-in high-precision 65kHz switching frequency oscillator with a spread spectrum function to optimize EMI performance. The chip operates in green energy-saving mode and hiccup mode to meet the requirements of Level VI energy efficiency and standby power consumption less than 75mW. The KP201A integrates complete protection functions, including: VDD undervoltage protection (UVLO), VDD overvoltage protection (OVP), CSOVP protection, cycle-by-cycle current limit, short-circuit protection (SCP), overload protection (OLP), internal over-temperature protection, externally adjustable over-temperature protection (OTP), soft start, VDD clamping, and CS pin open protection. Main Features • Supports discontinuous mode and continuous mode operation • ±1% constant voltage accuracy • Meets Level VI energy efficiency, standby power consumption <75mW • Fixed 65kHz switching frequency • Green energy-saving mode and hiccup mode operation • Ultra-low start-up and operating current • Integrated spread spectrum function to optimize EMI • Integrated current mode control with internal slope compensation • Package type SOT23-6 • Integrated self-recovery protection functions: • VDD undervoltage protection (UVLO) • VDD overvoltage protection (OVP) • CS overvoltage protection (CS OVP) • Internal over-temperature protection (OTP) • Externally adjustable over-temperature protection (OTP) • Cycle-by-cycle current limit • Overload protection (OLP) • Leading edge blanking (LEB) • CS pin open protection
