ZXLD1371QESTTC

Diodes ZXLD1371 is a high accuracy LED driver controller. The LED load current that can be delivered is dependent on the external MOSFET. The ZXLD1371, with its unique architecture utilizing only one current sense resistor, can be used as a Buck converter, Boost converter, and a Buck-Boost converter.The ZXLD1371 extends the minimum input voltage of the ZXLD1370 down to 5.0 V. This allows it to operate at lower input voltages than the 1370, making it better suited to applications that are subjected to large variances in their input voltages, such as automotive lighting and 12 VAC powered systems. Its 60 V maximum input voltage enables it to comfortably operate from 48 V rails, and in boost mode can drive LED chain voltages greater than 60 V.
