PRIMARY SIDE CONTROL SMPS FOR LED DRIVER
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 component count without
using opto-coupler, secondary feedback control, and loop
compensation circuit, which will reduce the BOM cost.
The output voltage can be set by the feedback resistor and the
output current can be set by peak current sensing resistor within
a certain output power range, which can meet the requirements
SOT-23-6L
of different solutions for driving LEDs in series or in parallel.
