High-power, high-voltage, programmable LED driver for automotive and general lighting applications
(Product News, 06 Feb 2008 )
Maxim Integrated Products has introduced the MAX16816, a high-voltage, programmable, high-brightness (HB) LED driver for automotive and general lighting applications. Far more versatile than competitive devices, the MAX16816 provides many user-programmable features through on-chip nonvolatile EEPROM registers. Using a microcontroller and a single-wire interface, the programming is done either at the factory or by the designer in the field.
The MAX16816 integrates all the building blocks necessary to implement fixed-frequency HBLED drivers with wide-range dimming control. It is configurable to operate as a step-down (buck), step-up (boost) or step-up/down (buck-boost) current regulator. The device also includes an integrated, differential current-sense amplifier and a floating dimming driver capable of driving an n-channel MOSFET.
The MAX16816 is specifically tailored to meet the requirements of the latest front light automotive designs, such as high- and low-beam assemblies, adaptive front light systems, daytime running lights (DRLs), and fog lamps. The device is also ideal for high-power flood lighting, down lighting, and projection systems that require high-current LED drive capabilities.
