MAX16801BEUA

LED Driver IC Overview

The MAX16801BEUA is an offline and DC-DC PWM controller designed for high-brightness LED drivers. It supports flyback, SEPIC, buck, and boost topologies with a fixed switching frequency of 262kHz. The device operates from an input voltage range of 85V to 265V AC or 10.8V to 24V DC. It features analog and PWM dimming capabilities and includes internal protection mechanisms. The component is housed in an 8-uMAX/uSOP surface-mount package and functions without an internal switch.

LED Driver IC Feature Summary

• Supports multiple converter topologies including flyback, SEPIC, buck, and boost for versatile driver designs
• Enables precise light control through combined analog and pulse-width modulation dimming interfaces
• Integrates comprehensive protection features to ensure reliable operation under varying load conditions

LED Driver IC Applications

• High-brightness LED lighting systems
• Offline AC/DC LED power supplies
• DC-DC LED backlight drivers

LED Driver IC Procurement Notes

Verify the specific suffix (e.g., +T) against the required packaging format, as tape-and-reel variants exist. Confirm RoHS compliance status via the manufacturer's current documentation. Check for obsolescence notices, as this part family has faced discontinuation actions. Ensure the selected variant matches the intended operating voltage range and topology requirements.

LED Driver IC Selection Notes

Select this controller for applications requiring flexible topology support and dual-mode dimming. Verify that the external components align with the 262kHz switching frequency constraints. Consider thermal performance within the 8-uMAX package for the target ambient temperature range. Compare against newer generations if long-term supply assurance is critical for the design lifecycle.
