MP3331GC-Z

LED Driver IC Overview

The MP3331GC-Z is a single-channel boost LED driver IC from Monolithic Power Systems, designed for white LED (WLED) applications such as phone camera flashes. It operates with an input voltage range of 2.7 V to 5.5 V and delivers a maximum output current of 2 A. The device functions at a switching frequency of 4 MHz and utilizes a WLCSP-9 package. It supports PWM dimming and includes I2C interface capabilities for control.

LED Driver IC Feature Summary

• Integrates a high-efficiency boost converter topology optimized for driving white LEDs in compact mobile devices.
• Features an I2C digital interface allowing precise configuration of flash intensity and timing parameters.
• Supports pulse-width modulation (PWM) dimming for flexible brightness control without color shift.

LED Driver IC Applications

• Smartphone camera flash systems
• Mobile device WLED backlighting
• Compact portable electronic lighting

LED Driver IC Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and lead-free status as per manufacturer standards. Confirm the WLCSP-9 package dimensions match your PCB footprint requirements. Ensure the design supports the 4 MHz switching frequency to manage electromagnetic interference appropriately within the target application constraints.

LED Driver IC Selection Notes

Select this component when a single-channel solution with integrated I2C control is required for high-current flash applications. Compare against the MP3336 series if dual-channel output or different packaging is necessary. Consider the 4 MHz frequency for smaller external inductor sizes compared to lower-frequency alternatives.

LED Driver IC Part Context

This part belongs to the MP3331 series of LED drivers from Monolithic Power Systems. It is distinct from the MP3336, which offers dual outputs, and the MP3301, which features a different package and lower current capability. The GC-Z designation specifies the WLCSP-9 package and compliance attributes.

LED Driver IC Replacement Considerations

The MP3336GC-Z serves as a related alternative but provides two output channels instead of one. Verify pin compatibility and software register mapping before substitution, as functional differences exist between single and dual-channel variants in this product family.
