MAX1910EUB

LED Driver IC Overview

The MAX1910EUB+ is a high-efficiency white LED charge pump driver from the MAX1912 family, designed for portable applications. It operates on an input voltage range of 2.7 V to 5.3 V and delivers up to 120 mA output current per channel. The device integrates a 750 kHz switching frequency charge pump, enabling efficient power conversion in a compact UMAX-10 surface-mount package. It supports both series and parallel LED configurations with low quiescent current consumption.

LED Driver IC Feature Summary

• Integrates a high-efficiency charge pump topology for driving white LEDs
• Supports flexible LED connection modes including series and parallel arrangements
• Operates within a wide single-supply voltage range suitable for battery-powered devices

LED Driver IC Applications

• White LED backlighting for cellular phones and PDAs
• Digital still cameras and MP3 players

LED Driver IC Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm RoHS compliance status and specific suffix variations (e.g., +T for tape/reel) against official datasheets. Check current lifecycle status as some variants may be discontinued or subject to limited supply constraints.

LED Driver IC Selection Notes

Select this component when designing portable electronics requiring efficient white LED illumination from a single-cell lithium-ion battery. Ensure the design accommodates the 120 mA output capability and 750 kHz switching frequency. Verify thermal performance within the specified -40°C to +85°C operating temperature range for the UMAX-10 package.

LED Driver IC Part Context

Part of the Maxim Integrated MAX191x series of LED drivers. Related parts include MAX1910EUB+T and MAX1912EUB+. These components share similar charge pump architectures but may differ in packaging options or specific electrical characteristics tailored for different portable application requirements.

LED Driver IC Replacement Considerations

Direct substitutes include MAX1910EUB+T for reel-packaged equivalents. Cross-reference with MAX1912EUB+ for similar functionality in the same family. Verify pin compatibility and electrical parameters before substitution.
