MAX16828ASA+

LED Driver IC Overview

The MAX16828ASA+ is a high-voltage, adjustable linear LED driver IC designed for high-brightness LED applications. It operates within an input voltage range of 6.5 V to 40 V and provides a regulated output current of up to 200 mA. The device features PWM dimming capability for brightness control and includes integrated short circuit and thermal protection mechanisms. Packaged in an 8-pin SO-EP (SOIC-Narrow) surface-mount package, it supports operation across a temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Supports PWM dimming for precise brightness control
• Integrates short circuit and thermal protection
• Operates with high-voltage inputs up to 40 V

LED Driver IC Applications

• High-brightness LED lighting systems
• General illumination drivers
• Industrial LED indicators

LED Driver IC Procurement Notes

Verify the specific suffix (+T vs +) against the required packaging format, as the datasheet indicates distinct packaging options such as tube or reel. Confirm availability status directly with authorized distributors, as supply constraints may apply. Ensure the selected variant matches the required operating temperature range and pinout configuration for the target PCB design.

LED Driver IC Selection Notes

Select this component when a single-channel linear driver is sufficient for low-to-medium power LED strings. The 200 mA output current rating suits applications requiring moderate brightness without complex switching topologies. Consider the thermal dissipation capabilities of the SO-EP package relative to the expected power loss under load conditions.

LED Driver IC Part Context

This part belongs to the MAX16828 series of linear LED drivers from Analog Devices/Maxim Integrated. It is engineered for simplicity and reliability in driving high-brightness LEDs where efficiency is secondary to cost and design simplicity compared to switching regulators.

LED Driver IC Replacement Considerations

Check for direct pin-compatible alternatives within the MAX1682x family, such as the MAX16836 for higher current requirements. Verify that any substitute maintains the same 40 V maximum input voltage and PWM dimming interface compatibility.
