Description
The ZXLD1370 is an LED driver controller IC for driving external MOSFETs to drive high current LEDs. It is a multi topology controller enabling it to efficiently control the current through series connected LEDs. The multi-topology enables it to operate in buck, boost and buck-boost configurations. The 60V capability coupled with its multi-topology capability enables it to be used in a wide range of applications and drive in excess of 15 LEDs in series.
