Description

Rapid advances in LED technology has led to

increases in their output current capabilities in

recent years. 0.350 A LEDs, for example, were

soon followed by 0.7 A LEDs, and then 1 A

devices appeared shortly thereafter. Currently,

LEDs with currents as high as several amps are

present on the market. However, these high

currents increase the requirements of the driving

circuitry of the LEDs, particularly in terms of

efficiency.

The STEVAL-ILL023V1 demonstration board is

based on the L6726A single phase PWM

controller, with two external MOSFETS for

synchronous rectification. Designed for 2.8 A

LEDs (1-3 in a series string), the main benefit of

the solution is its exceptional efficiency. Ease of

dimming and scalability to even higher currents

are additional advantages of the design.

The solution is also much safer with regard to

border conditions, since the current limit is based

solely on the selection of the MOSFETS.
