CAT4004VP2-GT3

Overview

The CAT4004VP2-GT3 is a four-channel LED driver IC from onsemi, designed for constant current regulation in lighting applications. It supports both boost and buck topologies with an input voltage range of 2.4 V to 5.5 V. The device provides adjustable output currents up to 40 mA per channel and features EZDim™ linear multi-step dimming capability. Packaged in an 8-TDFN (2x3) format, it operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates four independent constant current channels for driving multiple LEDs
• Supports flexible boost and buck converter topologies for various LED configurations
• Includes EZDim™ interface for simple linear multi-step dimming control

Applications

• General solid-state lighting fixtures
• LED backlighting systems
• Portable electronic device illumination

Procurement Notes

Verify the specific suffix VP2 against the official datasheet to confirm package type and tape/reel specifications. Ensure the design accommodates the 2.4 V to 5.5 V input range and thermal requirements for the TDFN-8 package. Cross-reference the EZDim pin configuration with the target controller interface.

Selection Notes

Select this component when a compact solution for four-channel LED control is required. It is suitable for designs needing both boost and buck flexibility within a single IC. Consider the 40 mA maximum output current limit and the specific dimming interface requirements before finalizing the schematic.
