Description
The STEVAL-ILL042V2 demonstration board is
an LED power supply in high PF flyback
configuration designed 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
for constant current control.
The L6562AT is a PFC controller which operates
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%
can be achieved.
Designed using the L6562A and the TSM101
controllers, this system offers several advantages
in terms of output current and voltage stability.
