60V HIGH ACCURACY 1.5A BUCK/BOOST/BUCK-BOOST LED DRIVER CONVERTER  
Description  
Pin Assignments  
The ZXLD1374 is an LED driver converter IC with integrated  
1.5A low side switch to drive high current LEDs. It is a multi-  
topology converter 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 16 LEDs in series.  
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.
