KP1032BNon-isolated Buck-Boost LED Power Switch
KP1032B is a highly integrated power switch with Buck-Boost constant current (CC) control for LED lighting applications.
KP1032B combines a 650V power MOSFET switch with a power controller in one chip. The IC also integrates high voltage startup/IC supply circuit and a novel transformer demagnetization circuit, which eliminates transformer auxiliary winding.
KP1032B integrates functions and protections of Under Voltage Lockout (UVLO), Cycle-by-cycle Current Limiting (OCP), Thermal Fold-back (OTP), LED Open/Short Protection, etc.
