Diodes Incorporated Announces a Versatile LED Driver that Increases Reliability of High Brightness Lamp Systems

Diodes Incorporated, a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete and analog semiconductor markets, today announces a multi-topology LED driver IC designed to increase the reliability of high brightness lamps in automotive, industrial, and commercial lighting systems.

The ZXLD1370 LED driver controller operates in buck, boost, and buck-boost modes. It combines patent pending control loops and high-side current sensing to ensure accurate current control of LED strings.

With an extended 6V to 60V operating input voltage range and a typical 1% output current tolerance in all topologies, the driver is capable of delivering the high current levels and tight inter-lamp luminance-matching required by high brightness LED systems. LED reliability and longevity is improved by active LED thermal management achieved via a dedicated external thermistor input, and by fault diagnosis outputs that report the status of LED driver and load.

The ZXLD1370 LED driver controller, used with an external MOSFET, provides a single driver solution capable of supporting a very wide range of LED configurations and current requirements. It supports high accuracy dimming through DC dimming and PWM dimming options. With a dedicated PWM input, the driver offers a 1000:1 dynamic dimming range at 1 kHz. This allows for high accuracy control of color mixing and excellent resolution at low brightness levels.

The device's 1 MHz switching frequency capability with 100 kHz low frequency clamp also means a reduction in the size of the external inductor and simpler design of input EMI filters should they be required. Further information is available on the Company's website at www.diodes.com.
