The ZXLD1374Q 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 ZXLD1374Q 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 ZXLD1374Q 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 ZXLD1374Q is qualified to AEC-Q100 and is automotive grade supporting PPAPs.
