MAXIM INTEGRATED / ANALOG DEVICES MAX16822BASA High-Brightness LED Driver
The MAX16822BASA+ is a high-brightness LED driver operating at a switching frequency of 2MHz, featuring an integrated MOSFET and high-side current sensing in an 8-pin NSOIC package. This step-down, constant-current LED driver provides a cost-effective solution for various lighting applications including interior and exterior lighting, architectural and ambient lighting, heads-up displays, indicator and emergency lighting, LED bulbs, and other LED illumination needs. It operates from a input voltage range of 6.5V to 65V and can deliver an output current up to 350mA at 125°C or up to 500mA at 105°C. The device uses a high-side current sense resistor to adjust the output current, and a dedicated PWM input enables pulsed LED dimming across a wide brightness range. Its high-side current sensing and integrated current setting circuitry reduce external component requirements while providing an average output current accuracy of ±3%. The hysteretic control ensures excellent input supply rejection, fast response to load changes, and supports a 30% current ripple. Features include a supply current of 350µA, thermal foldback, over-temperature protection, and minimal external components with onboard 65V, 0.85Ω power MOSFET, resistor-programmable current, and integrated current sense circuitry with a 200mV reference. Suitable for automotive, industrial, and general lighting applications.
