AUTOMOTIVE PLIANT 60V HIGH ACCURACY BUCK/ BOOST/BUCK-BOOST LED DRIVER-CONTROLLER
Description
The ZXLD1371Q 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.
The ZXLD1371Q is a modified hysteretic controller using a patent pending control scheme providing high output current accuracy in all three modes of operation. High accuracy dimming is achieved through DC control and high frequency PWM control.
The ZXLD1371Q 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 ZXLD1371Q has been qualified to AEC-Q100 Grade 1 and is Automotive Grade supporting PPAPs.
