MAX16819ATT+T

LED Driver IC Overview

The MAX16819ATT+T is a step-down constant-current high-brightness LED driver from Analog Devices. It operates within a 4.5V to 28V input voltage range and features an integrated 5V/10mA on-board regulator. The device utilizes a hysteretic control algorithm for excellent input-supply rejection and fast transient response. It supports up to 2MHz switching frequency, enabling compact component sizing. High-side current sensing ensures ±5% LED current accuracy with minimal external components.

LED Driver IC Feature Summary

High-side current sense minimizes external component count while delivering precise LED current regulation
Dedicated PWM dimming input enables wide-range pulsed dimming capabilities
Hysteretic control architecture eliminates the need for external compensation networks

LED Driver IC Applications

Automotive interior lighting systems
Architectural illumination fixtures
Ambient lighting solutions

LED Driver IC Procurement Notes

Verify authenticity through authorized channels due to limited supply status. Confirm package integrity upon receipt as parts may be subject to special ordering constraints. Ensure compatibility with existing thermal management designs given the operating temperature range specifications.

LED Driver IC Selection Notes

Select this component for applications requiring wide input voltage flexibility and high efficiency. The integrated regulator simplifies power distribution. Consider the 2MHz switching frequency for size-constrained designs. Verify that the hysteretic control meets stability requirements for specific load conditions.

LED Driver IC Part Context

This part belongs to the MAX16819/MAX16820 series of high-brightness LED drivers. It shares architectural similarities with other Maxim Integrated LED controllers but is distinguished by its specific ripple characteristics and hysteretic control method designed for automotive and general illumination markets.
