PartNumber: None
The KP107WSPA is a highly integrated non-isolated quasi-resonant (QR) buck constant-current LED controller designed for offline LED lighting applications. It features an integrated high-voltage startup and VDD power supply circuit, eliminating the need for an auxiliary winding and reducing external component count. The controller provides high-accuracy constant-current regulation (±5%), excellent efficiency through quasi-resonant operation, and reliable protection features for robust LED driver designs. It is ideal for high-power LED lighting such as bulbs, panel lights, downlights, and industrial lighting.
