The ZXLD1350ET5 is a 30V LED Driver with integrated switch and high side current sense. This hysteretic mode inductive step-down converter operates from an input supply from 7 to 30V driving single or multiple series connected LEDs efficiently external adjustable output current up to 350mA. The output current can be adjusted by applying a DC voltage or a PWM waveform. 100:1 adjustment of output current is possible using PWM control. Applying a voltage of 0.2V or lower to the ADJ pin turns the output off and switches the device into a low current standby state.
