60V HIGH ACCURACY BUCK/BOOST/BUCK-BOOST LED DRIVER-CONTROLLER WITH AEC-Q100

Description

Pin Assignments

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.

TSSOP-16EP

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.
