KP22035
KP22035 A high-performance, high-efficiency AC-DC power converter suitable for wide voltage output. KP22035 is a high-performance current mode PWM converter chip for offline flyback converters. The chip adopts green energy-saving mode, hiccup mode, and light-load valley conduction mode to optimize system efficiency and easily meet the requirements of Level VI energy efficiency. The chip supports 8-70V VDD power supply, which is convenient for meeting the requirements of wide voltage output power supplies. KP22035 integrates a high-precision 65kHz switching frequency oscillator, and integrates functions such as slope compensation, soft start, frequency jitter, and loop gain adjustment. The stability, reliability, and electromagnetic compatibility of the system are greatly improved. KP22035 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, leading edge blanking (LEB), and CS pin open-circuit protection.
