Product Description

High PF non-isolated BUCK constant voltage built-in MOS chip, non-isolated dimming without stroboscopic chip

KP28162SGA is a constant voltage output power switch for dimming and toning LED applications. The chip adopts quasi-resonant mode and adaptively adjusts the output voltage, which not only meets the voltage requirement of the linear constant current after the stage, but also improves the efficiency of the system. The KP28162SGA has an integrated high-voltage 500V power MOSFET and high-voltage start and power supply circuit, simplifying system design and production costs. The chip has a light load frequency reduction mode, which can improve the stability of the system under light load or no load, and has a high efficiency. KP28162 is integrated with complete protection functions, including: VDD undervoltage protection (UVLO), output overvoltage protection (OVP), output short circuit protection (SCP), cycle current limit (OCP), built-in overheat protection, leading edge blanking (LEB), etc.
