MAX16822BASA+

LED Driver IC Overview

The MAX16822BASA+ is a high-brightness LED driver IC featuring a 2 MHz switching frequency. It integrates a synchronous buck converter capable of delivering up to 350 mA output current with a single channel. The device supports PWM dimming for brightness control and operates within an extended temperature range. Packaged in an 8-pin SOIC, it offers a compact solution for efficient LED lighting applications.

LED Driver IC Feature Summary

• Integrates a synchronous step-down (buck) DC-DC converter topology for high efficiency.
• Supports pulse-width modulation (PWM) dimming for precise brightness adjustment.
• Features a fixed 2 MHz switching frequency to minimize external component size.

LED Driver IC Applications

• High-brightness LED lighting systems
• General illumination drivers
• Portable lighting devices

LED Driver IC Procurement Notes

Verify the specific suffix 'BASA+' against the manufacturer's official datasheet to confirm pinout and thermal characteristics. Ensure the design accounts for the 8-pin SOIC package dimensions and thermal dissipation requirements. Cross-reference the 350 mA current limit with application load needs to prevent overcurrent conditions during operation.

LED Driver IC Selection Notes

Select this component when a compact, high-frequency buck LED driver is required. The 2 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the input voltage range and desired LED string configuration align with the device's synchronous buck architecture capabilities.

LED Driver IC Part Context

This part belongs to the Maxim Integrated line of power management solutions, now under Analog Devices. It is designed specifically for driving high-brightness LEDs efficiently. The device simplifies design by integrating the power switch and control logic into a single small footprint.

LED Driver IC Replacement Considerations

Consult official substitution guides for compatible parts within the same product family. Verify electrical compatibility and pinout alignment before replacing existing designs.
