Description
The STEVAL-ILL076V1 product evaluation board
implements an offline power converter based on
a single-stage high-PF flyback topology using the
HVLED001 controller.
A very slim form factor is achieved using
innovative magnetic parts. Output voltage is
controlled by the primary side, reducing the need
for costly opto-couplers. The precision of the
HVLED001's PSR feature together with the
innovative structure of the transformer make
output voltage regulation very accurate against
load and line changes.
Very high efficiency is obtained and a full set of
protection features are implemented, including
protection against output short-circuit and input
overvoltage.
Conducted EMI is pre-screened and clearance
and creepage distances are within EN60950
safety standards.
Power factor and THD measurements are
optimized to be higher than 0.95 and lower than
10%, respectively, at full load.
The main application for this converter is bus
power supply for an LED string driver providing 4
kV of isolation.
