6. Conclusions
Infineon Technologies’ LED Driver family offers
the end user an easy, cost-effective way to
stabilize LED current in fixed, portable or
automotive LED display applications. DC power
consumption is minimized, as compared to LED
driver circuits employing resistors for current
stabilization.
coefficient of these LED Drivers helps to prevent
thermal runaway conditions in LED displays.
