MAXIM INTEGRATED / ANALOG DEVICES MAX16822AASA High Brightness LED Driver
The MAX16822AASA+ is a high-brightness LED driver operating at 2MHz with an integrated MOSFET and high-side current sensing, housed in an 8-pin NSOIC package. It is a step-down (buck) constant current driver designed to provide a cost-effective solution for various LED lighting applications such as interior and exterior lighting, architectural and ambient lighting, heads-up displays, indicator lights, emergency lighting, and LED bulbs. The device supports input voltages from 6.5V to 65V and can deliver an output current of up to 350mA at 125°C or up to 500mA at 105°C. It features programmable output current via a high-side sense resistor and offers additional dimming options through dedicated PWM input or linear dimming, enabling wide brightness control. Its hysteretic control method ensures excellent supply rejection and fast transient response, with a typical current ripple of 10%. The MAX16822AASA+ includes a 65V, 0.85Ω onboard power MOSFET, thermal foldback protection, and thermal shutdown to prevent overheating. It consumes approximately 350μA supply current, operates in the automotive temperature range from -40°C to 125°C, and minimizes component count for space and cost savings.
