MAX8830EWE+

LED Driver IC Overview

The MAX8830EWE+ is an LED light management IC integrating a 400mA PWM step-up DC-DC converter, a 320mA flash LED current sink, and four programmable LED current sinks. It operates with a fixed 1MHz switching frequency and features an internal switching MOSFET and synchronous rectifier. The device supports I2C programming for output voltage (3.8V to 5.2V), flash current (Off to 320mA), and movie current (Off to 160mA). Each of the four LED sinks provides individual regulation from Off to 10mA in 32 steps. It includes open/short detection, thermal shutdown, and consumes less than 1µA in shutdown mode.

LED Driver IC Feature Summary

• Integrates a high-efficiency step-up DC-DC converter with on-chip FET and synchronous rectifier
• Provides individually programmable LED current sinks with low dropout voltage
• Supports I2C interface for precise control of flash, movie, and auxiliary LED currents
• Includes safety features such as open/short LED detection and thermal-shutdown protection

LED Driver IC Applications

• Cell phones and smartphones
• PDAs and MP3 players

LED Driver IC Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm package integrity and MSL level compliance before assembly. Check for obsolescence status as legacy components may have limited availability. Ensure ESD handling protocols are followed during storage and installation.

LED Driver IC Selection Notes

Select this IC for applications requiring integrated LED management with minimal external components. The fixed 1MHz switching frequency allows for small inductor sizes. Verify that the required flash and auxiliary LED currents fall within the specified programmable ranges. Ensure the system design accommodates the UCSP package dimensions and thermal requirements.
