Description

The

a constant LED current. The constant current regulation is especially beneficial for LED color accuracy and longer lifetime.

The controller concept of the

Flyback by simply adjusting the external components. The

can be achieved with analog or PWM input.The switching frequency is adjustable in the range of 100 kHz to 500 kHz and

can be synchronized to an external clock source. The

loop maintained by small external compensation components. The integrated soft start feature limits the current peak as

well as voltage overshoot at start-up. This IC is suited for use in the harsh automotive environments and provides output

overvoltage protection and device overtemperature shutdown.
