Description
The STEVAL-ISA080V1 demonstration board is a
90 W, wide range mains, power factor corrected
AC-DC power supply.
The architecture is based on a two-stage
approach: a front-end PFC pre-regulator and a
downstream multi-resonant half bridge converter.
Both stages are controlled by the new L6585DE
that integrates PFC and half-bridge control
circuits and the relevant drivers.
Although this new device is dedicated to manage
electronic ballast, it’s possible to use it also for HB
LLC resonant converter.
The PFC section achieves current mode control
operating in transition mode, offering a highly
linear multiplier including a THD optimizer that
allows for an extremely low THD, even over a
large range of input voltages and loading
conditions.
