A Product Line of Diodes Incorporated ZXLD1374 60V HIGH ACCURACY 1.5A BUCK/BOOST/BUCK-BOOST LED DRIVER CONVERTER WITH AEC-Q100 Description The ZXLD1374 is a 60V LED driver with integrated 1.5A low side switch to drive high current LEDs. It is a multi-topology converter enabling it to operate in Buck, Boost and Buck-boost configurations; efficiently controlling the current of up to 16-series connected LEDs. The ZXLD1374 is a modified hysteretic converter using a patent pending control scheme providing high output current accuracy in all three topologies. High accuracy dimming is achieved through DC control and high frequency PWM control. The ZXLD1374 uses two pins for fault diagnosis.
