KP2813A
KP2813A High PF, Low THD, Primary Side Controlled Flyback Constant Voltage Controller KP2813A is a high power factor, low total harmonic distortion, primary side controlled flyback constant voltage controller. The chip has a built-in high-voltage startup circuit to meet the requirements of fast startup and ultra-low standby power consumption. KP2813A adopts a quasi-resonant operating mode, which can achieve high system efficiency and good EMC performance. The chip can set the minimum operating frequency to ensure the stability of the output voltage under full load conditions and meet the requirements of low standby power consumption. KP2813A is equipped with a multi-stage adjustable adaptive output voltage limiting mechanism to accelerate the load dynamic response speed and meet different application needs. KP2813A integrates complete protection functions, including: VDD undervoltage protection (VDD UVLO), VDD overvoltage protection (VDD OVP), input undervoltage protection (BOP), output overvoltage protection (OVP), output undervoltage protection (UVP), cycle-by-cycle current limit (OCP), abnormal overcurrent protection (AOCP), overload protection (OLP), short-circuit protection (SCP), built-in overtemperature protection (OTP), and leading edge blanking (LEB).
