Kiwi Instruments KP14652SPA

The KP1465X series is a highly integrated buck-type constant-current LED power switch. The chip employs a quasi-resonant operating mode, eliminating the need for an auxiliary winding for demagnetization detection. The KP1465X also integrates a proprietary dimming technology capable of delivering high-accuracy PWM signal dimming. The KP1465X internally integrates a 500V high-voltage MOSFET and a 650V high-voltage power supply circuit, simplifying system design and reducing production costs. The chip incorporates high-precision inductor current sensing technology to achieve highly accurate constant-current output, with excellent line voltage and load regulation performance. The KP1465X integrates comprehensive protection features to ensure safe and reliable system operation, including: UVLO, cycle-by-cycle OCP, OTP, OVP, and LED open-circuit and short-circuit protection.
