LED Driver IC datasheet and documents for MAX16819ATT+
LED Driver IC Overview
The MAX16819ATT+ is a step-down constant-current high-brightness LED driver designed for automotive and architectural lighting. It operates from an input voltage range of 4.5V to 28V and features a dedicated PWM dimming control input. The device utilizes a hysteretic control algorithm to ensure excellent input-supply rejection and fast response during load transients. It includes a 5V/10mA on-board regulator and offers ±5% LED current accuracy with adjustable constant current settings.
LED Driver IC Feature Summary
- Hysteretic control algorithm eliminates the need for external compensation components
- Integrated 5V/10mA on-board regulator reduces external component count
- Dedicated PWM input enables wide-range pulsed dimming capabilities
LED Driver IC Applications
- Automotive interior and exterior lighting
- Architectural lighting systems
- Ambient lighting applications
LED Driver IC Procurement Notes
Verify the specific suffix 'ATT+' against the official Analog Devices datasheet to confirm package type and temperature rating. Ensure compatibility with the required input voltage range of 4.5V to 28V. Confirm that the hysteretic control topology meets the design requirements for input-supply rejection and transient response without additional compensation networks.
LED Driver IC Selection Notes
Select this component when a cost-effective, single-output step-down solution is required for high-brightness LEDs. It is suitable for designs needing a wide input voltage range and integrated regulation. Consider the ±5% current accuracy and 2MHz switching frequency for applications prioritizing small passive component sizes and precise current control.
LED Driver IC Part Context
This part belongs to the MAX16819/MAX16820 family of high-brightness LED drivers. While the MAX16820 variant offers 10% inductor current ripple, the MAX16819 provides 30% ripple. Both share similar features such as high-side current sensing and PWM dimming, but differ in ripple specifications and potentially internal tuning parameters.
LED Driver IC Replacement Considerations
The MAX16820ATT+ is a related device within the same family, offering different inductor current ripple characteristics (10% vs 30%). Verify if the ripple difference impacts the specific application requirements before substitution.
