60V HIGH ACCURACY BUCK/BOOST/BUCK-BOOST LED DRIVER CONTROLLER

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.

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.

TSSOP-16 EP

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.
