Diodes Incorporated ZXLD1370Q

Description

The ZXLD1370Q is an LED driver controller IC for driving external MOSFETs to drive high current LEDs. It is a multi-topology controllerenabling 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 ZXLD1370Q 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 ZXLD1370Q uses two pins for fault diagnosis. A flag output highlights a fault, while the multi-level status pin gives furtherinformation on the exact fault.The ZXLD1370Q has been qualified to AEC-Q100 Grade 1 and is automotive grade supporting PPAPs.
