ZXLD1356ET5TA

The ZXLD1356ET5TA is a continuous mode inductive Step-Down Converter designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage. The LED driver device operates from an input supply between 6 and 60V and provides an externally adjustable output current of up to 550mA. Depending upon supply voltage and external components, this can provide up to 30W of output power. Output current can be adjusted above or below the set value, by applying an external control signal to the ADJ pin. Enhanced output current dimming can be achieved by applying a PWM signal to the ADJ pin.

• Typically better than 0.8% output current accuracy
• Simple and with low part count
• Single pin ON/OFF and brightness control using DC voltage or PWM
• PWM resolution up to 1000:1
• High efficiency up to 97%
• Inherent open-circuit LED protection
