60V HIGH ACCURACY BUCK/BOOST/BUCK-BOOST
LED DRIVER-CONTROLLER WITH AEC-Q100
Description
The ZXLD1370 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 ZXLD1370 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 ZXLD1370 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.
