STEVAL-ILL042V1 60 W high power factor flyback LED driver demonstration board based on the L6562AT and TSM101
The STEVAL-ILL042V1 demonstration board is a LED power supply in high PF flyback configuration able to drive a 60 W LED array. The board is based on the L6562AT and the TSM101 controller.
This configuration uses an isolated feedback with an optocoupler and a secondary side reference/error amplifier, the TSM101, for voltage and current regulation.
The TSM101 includes two op-amps. One op-amp is used for constant voltage control and the other one for constant current control.
The L6562AT is a PFC controller operating in transition mode. The highly linear multiplier includes a special circuit which is able to reduce AC input current distortion, allowing wide-range mains operation with an extremely low THD, even over a large load range.
Efficiency is high at heavy load, more than 90% is achievable.
This system, designed using the L6562AT and the TSM101 controller, offers several advantages in terms of output current and voltage stability
