SD6855TR Description
SD6855/6 is a primary side control SMPS for LED driver with accurate constant voltage, constant current (CV/CC) control loop for high average efficiency and reliability. Using SD6855/6 for system design can reduce the ponent count without using opto-coupler, secondary feedback control, and loop pensation circuit, which will reduce the BOM cost. The output voltage can be set by the feedback resistor and the output...
