MP3313GC-Z

LED Driver IC Overview

The MP3313GC-Z is a three-channel step-up white LED driver IC from Monolithic Power Systems, designed for LCD panel backlighting. It operates within a 2.7 V to 5.5 V input voltage range and supports output voltages up to 38 V. The device features adjustable switching frequencies of 500 kHz or 1 MHz and delivers an output current of 25 mA per channel. It utilizes a WLCSP-12 package and functions across a temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Supports linear and exponential analog dimming control via I2C interface
• Integrates internal power switches in a boost topology
• Provides independent brightness control for three output channels

LED Driver IC Applications

• Virtual reality (VR) display backlighting
• LCD panel illumination systems
• Mobile device screen backlight drivers

LED Driver IC Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance status as documented by the manufacturer. Confirm the WLCSP-12 package dimensions against your PCB footprint requirements. Ensure the design supports the required I2C communication lines for dimming control. Validate that the input voltage supply remains within the specified 2.7 V to 5.5 V operational window.

LED Driver IC Selection Notes

Select this component when designing compact backlight solutions requiring multi-channel LED driving with precise analog dimming capabilities. The integrated boost converter eliminates external inductors in some configurations, saving board space. Consider the thermal performance limits given the small form factor and maximum power dissipation specifications provided in the datasheet.

LED Driver IC Part Context

This part belongs to the MP3313 series of LED lighting drivers. It is distinct from single-channel variants like the MP3301 and two-channel models such as the MP3312. The GC-Z designation specifies the pin-compatible WLCSP-12 package variant intended for high-density surface mount applications.

LED Driver IC Replacement Considerations

Direct substitutes include other MPS three-channel WLED drivers within the same family. Verify pin compatibility and electrical parameters before swapping with similar parts from different manufacturers.
