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
Pin Assignments
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. A flag output
highlights a fault, while the multi-level status pin gives further
information on the exact fault.
The ZXLD1374 has been qualified to AEC-Q100 Grade 1 enabling
operation in ambient temperatures from -40 to +125°C .
