AL1788
LOW STANDBY POWER PFC CONTROLLER Description Pin Assignments NEW PRODUCT The 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. Top View With either Flyback or Buck topology, AL1788 system supports high
efficiency, high Power Factor (PF>0.9) and low Total Harmonic
Distortion (THD 0.9) and Low THD ( …
