Description
The ZXLD1350 is a hysteretic mode inductive step-down
converter with integrated switch and high side current sense.
It operates from an input supply from 7V to 30V driving single
or multiple series connected LEDs efficiently external
adjustable output current up to 350mA.
The ZXLD1350 has been qualified to AECQ100 grade 2
allowing it to operate at ambient temperatures from -40 to
105°C.
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.
