The MAX16832AASA+ is a single-channel, high-brightness LED driver from Analog Devices, built as a DC-DC step-down (buck) regulator with integrated switching MOSFET. It delivers up to 700 mA to an LED string from a supply rail spanning 6.5 V to 65 V, making it a fit for automotive lighting (headlamps, daytime running lights, interior), industrial signage, and general-purpose constant-current LED fixtures. PWM dimming input allows direct brightness control from a microcontroller or PWM source.
The 6.5 V to 65 V input range covers automotive and industrial buses without an external pre-regulator. The 700 mA per channel output is a single-string constant-current source.
