KP2201
KP2201 Suitable for wide voltage output, integrated high-voltage start-up function current mode PWM drive controller KP2201 is a high-performance current mode PWM controller for off-line flyback converters. The chip integrates high-voltage start-up, input power-down detection, and X capacitor discharge functions to meet the requirements of fast start-up and ultra-low standby (typical value <30mW@230Vac). The chip adopts green energy-saving mode, hiccup mode, light load valley conduction mode, and heavy load entering CCM mode to optimize system efficiency, and can easily meet the requirements of Level VI energy efficiency. KP2201 built-in high-precision 65KHz switching frequency oscillator, integrated slope compensation, soft start, frequency jitter technology, loop gain adjustment and other functions. The stability, reliability, and electromagnetic compatibility of the system are greatly improved. In addition, the ultra-wide operating voltage of VDD is very suitable for adapters with wide voltage output such as PD fast charging. KP2201 integrates complete protection functions, including: VDD undervoltage protection (UVLO), VDD overvoltage protection (VDD OVP), input undervoltage protection (Brownout), X capacitor discharge protection, output overvoltage protection (OVP), output undervoltage protection (UVP), cycle-by-cycle current limit (OCP), overload protection (OLP), short-circuit protection (SCP), built-in overtemperature protection, external overtemperature protection, abnormal overcurrent protection (AOCP), leading edge blanking (LEB), CS pin open circuit protection, VDD clamp protection, etc.
