KP1501AVP is a low cost, highly integrated PWM power switch for non-isolated buck applications.KP1501AVP combines a 500V power MOSFET with the ON/OFF PWM controller in one chip. The IC can achieve high precision 5V default Output at universal AC input. In KP1501AVP, T off_min is set to 20μs with frequency shuffling. The IC has built- in green mode control for light and zero loadings, which can achieve less than 50mW standby power.KP1501AVP integrates functions and protections of Under Voltage Lockout (UVLO), Cycle-by-cycle Current Limiting (OCP),On-chip Thermal Shutdown (OTP), Abnormal Over Current Protection (AOCP), Over Load Protection(OLP) Short Load Protection (SLP), etc.
