A multi-topology LED driver ZXLD1374 has designed by Diodes Incorporated , to increase the performance of high brightness automotive, industrial and commercial lighting systems.
With the integrated 60V power MOSFET switch, the ZXLD1374 LED driver can produce a maximum LED current of 1.5A.
An extended input voltage range of 6V to 60V combined with a typical 1% output current tolerance in all topologies means the driver readily supports the high current levels and tight inter-lamp luminance-matching needed by high brightness LED systems.
With dedicated DC dimming and PWM dimming pins, the ZXLD1374 provides a 1000:1 dynamic dimming range at 500Hz, ensuring highly accurate control of color mixing and excellent resolution at low brightness levels.
Moreover, the IC's 1MHz switching frequency capability with 100kHz low frequency clamp also helps reduce the size of the external inductor and simplify the design of any input EMI filters.
