KP220X
KP220X A current mode PWM driver controller suitable for wide voltage output The KP220X is a high-performance current mode PWM controller for offline flyback converters. The chip adopts green energy-saving mode, hiccup mode, light load valley conduction mode, and heavy load CCM mode to optimize system efficiency, easily meeting the requirements of Level VI energy efficiency. The KP220X integrates a high-precision 65kHz/100kHz switching frequency oscillator, and incorporates slope compensation, soft start, frequency dithering technology, and loop gain adjustment functions. The stability, reliability, and electromagnetic compatibility of the system are greatly improved. In addition, the VDD operating voltage range is very suitable for adapters with wide voltage output, such as PD fast charging. The KP220X integrates complete protection functions, including: VDD undervoltage protection (UVLO), VDD overvoltage protection (VDD OVP), 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, leading edge blanking (LEB), and CS pin open-circuit protection.
