MAX77387EWP+T

LED Driver IC Overview

The MAX77387EWP+T is a switching voltage regulator designed as a dual-output flash driver. It operates within an input voltage range of 2.5V to 5.5V and provides regulated outputs between 2.3V and 5.2V. Each channel delivers up to 1A for flash applications, utilizing a boost topology with an internal switch. The device supports analog and PWM dimming at a fixed frequency of 4MHz. It is housed in a 20-WLP package and functions reliably across temperatures from -40°C to +85°C.

LED Driver IC Feature Summary

• Dual independent LED driver channels providing dedicated control for flash illumination
• Integrated high-efficiency boost converter with internal power switch
• Supports both analog and pulse-width modulation (PWM) dimming methods

LED Driver IC Applications

• Camera module flash drivers
• Mobile device illumination systems
• Compact imaging subsystems requiring high peak current

LED Driver IC Procurement Notes

Verify the specific suffix 'EWP+T' against official Analog Devices documentation to confirm the 20-WLP packaging and tape-and-reel quantity. Ensure compatibility with the target board's thermal design and input voltage constraints before finalizing procurement orders.

LED Driver IC Selection Notes

Select this component when designing camera flash circuits requiring two independent high-current outputs from a single supply rail. It is suitable for space-constrained mobile devices where a compact WLP footprint and integrated boost functionality reduce external component count.

LED Driver IC Part Context

This part belongs to the Maxim Integrated line of specialized power management ICs, now under Analog Devices. It addresses the specific need for efficient, high-brightness LED driving in portable electronics, distinguishing itself through its dual-channel architecture and small form factor compared to single-channel alternatives.

LED Driver IC Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic equivalents may lack the precise dual-channel synchronization or specific dimming characteristics required for camera flash applications.
