Diodes Incorporated ZXLD132X DC-DC Converter Series LED Drivers
Diodes Incorporated ZXLD132X inductive DC-DC converter series LED drivers provide performance capabilities for the next generation of high brightness LEDs. The three flexible devices drive single or multiple LEDs with currents from 700mA through 1.5A, in buck, boost, and buck/boost configurations. Housed in a tiny 3mm X 4mm DFN package, the drivers can reduce the circuit footprint of existing solutions up to 50%.
