AL1788 is a high performance AC/DC Power Factor Correction (PFC) controller targeting at LED lighting applications. Based on Primary Side Regulation (PSR) implementation, AL1788 does not require opto-coupler and any secondary feedback circuit to save overall BOM cost. It operates at Quasi-Resonant (QR) mode where MOSFET is turned on at the valley of the drain voltage, which minimizes switching loss to result in high efficiency.
