KP223XXA series
KP223XXA High-performance, high-efficiency, quasi-resonant ACDC power converter KP223XXA is a high-performance quasi-resonant current mode PWM converter chip for offline flyback converters. The chip integrates a high-voltage startup circuit to achieve fast startup and ultra-low standby performance. The chip supports 8-40V VDD power supply, which is convenient for meeting the requirements of wide voltage output power supplies. KP223XXA has a built-in high-precision 80kHz switching frequency oscillator, and has frequency modulation and current peak modulation functions, which can optimize EMI performance. The chip combines quasi-resonant control mode, green energy-saving mode and hiccup mode operation to optimize efficiency across the entire range, achieving standby power consumption less than 30mW and meeting the requirements of Level VI energy efficiency. KP223XXA integrates complete protection functions, including: VDD undervoltage protection (UVLO), VDD overvoltage protection (VDD OVP), input undervoltage protection (Brownout), input overvoltage protection (LOVP), output overvoltage protection (OVP), cycle-by-cycle current limit (OCP), abnormal overcurrent protection (AOCP), overload protection (OLP), output overcurrent protection (SOCP), short-circuit protection (SCP), built-in overtemperature protection (OTP), soft start, leading edge blanking (LEB), etc.
