Description

The STEVAL-ILL043V1 demonstration board is a

high-PF flyback configuration in order to drive a

new design of the 75 W LED array based on the

L6562A controller, with a much reduced BOM

cost.

This configuration uses an isolated feedback with

an optocoupler and a secondary side

reference/error amplifier. The inverse buck

converter based on the L6562A is used for

constant voltage and constant current control in

double dimmable channels.

The L6562A is a PFC controller operating in

Transition mode. The highly linear multiplier

includes a special circuit, able to reduce AC input

current distortion, that allows wide-range-mains

operation with an extremely low THD, even over a

large load range.

The inverse buck converter shows good

performance in terms of power switch control and

conditioning circuitry signal for the current

sensing. In fact, this topology of converter allows

easy driving of the switch referred to ground by

using an L6562A driver.

L6562A with two dimmable strings

An integrated auxiliary power supply provides an

energy saving action and a remote control

monitoring function for the system.

This ballast designed by using the L6562A and

the buck inverse converter offers more

advantages in terms of output current and voltage

stability.

The key benefit is the very high efficiency that, at

full load, is almost 90%.
