LED Driver IC datasheet and documents for MAX8678ETE+

MAX8678ETE+

LED Driver IC Overview

The MAX8678ETE+ is a power management IC integrating a high-efficiency adaptive switched-capacitor charge pump for white LEDs and an audio loudspeaker amplifier. It operates on a supply voltage range of 2.7V to 5.5V with a switching frequency of 1MHz. The device is housed in a 16-WFQFN exposed pad package and supports an operating temperature range from -40°C to +85°C.

LED Driver IC Feature Summary

Integrates a high-efficiency adaptive charge pump for driving white light-emitting diodes.
Includes a built-in audio loudspeaker amplifier.
Operates at a fixed switching frequency of 1MHz.

LED Driver IC Applications

White LED backlighting in portable devices
Audio output stages in mobile electronics

LED Driver IC Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm the specific suffix 'ETE+' matches design requirements, as it denotes the tube packaging variant. Ensure compatibility with the 16-WFQFN exposed pad footprint during PCB layout review.

LED Driver IC Selection Notes

Select this component when simultaneous LED illumination and audio amplification are required within a single integrated solution. The 1MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the input voltage range aligns with the system's battery or supply characteristics.

LED Driver IC Part Context

This part belongs to the Maxim Integrated portfolio, now under Analog Devices Inc., focusing on power management solutions for portable consumer electronics. The MAX8678 series specifically targets applications requiring efficient lighting control alongside audio functionality in compact form factors.

LED Driver IC Replacement Considerations
