Overview
The IS31FL3197-CLS2-TR is a charge pump LED driver IC from Lumissil Microsystems, designed for automated RGBW lighting effects. It features four DC/DC regulator outputs with I2C dimming control and a maximum output current of 10 mA per channel. The device operates within an input voltage range of 2.7 V to 5.5 V and supports a communication frequency of up to 400 kHz. Packaged in a compact 16-WLCSP (1.88x1.8 mm) format with a 0.4 mm ball pitch, it integrates programmable sequence operations for efficient LED matrix driving.
Feature Summary
- Integrates a charge pump architecture to support automated RGBW lighting effect sequences
- Provides independent I2C dimming control for precise brightness management across channels
- Utilizes a compact WLCSP package design suitable for space-constrained PCB layouts
Applications
- Automated RGBW lighting systems requiring programmable color sequences
- Compact consumer electronics with limited board space for LED drivers
- I2C-controlled intelligent lighting modules
Procurement Notes
Verify the specific suffix CLS2 against the manufacturer's latest datasheet to confirm pinout and electrical specifications. Ensure compatibility with the target I2C bus voltage levels and check for any recent product change notifications regarding the WLCSP package dimensions or thermal characteristics before finalizing the design.
Selection Notes
Select this component when a low-profile solution is required for driving RGBW LEDs with integrated charge pump functionality. It is appropriate for designs needing programmable hardware sequences rather than MCU-driven PWM. Verify that the 10 mA output current meets the load requirements and that the 1.88x1.8 mm footprint fits the available PCB area.
Part Context
This part belongs to the IS31FL31xx series of industrial FxLED drivers from Lumissil Microsystems. These devices are characterized by wide LED support ranges and EMI noise reduction technologies. The IS31FL3197 specifically targets applications requiring compact form factors and integrated power regulation for multi-color LED matrices.
Replacement Considerations
No direct public substitute part numbers are confirmed in the provided documentation. Designers should evaluate other members of the IS31FL31xx series or consult Lumissil for updated alternatives if this component is no longer recommended for new designs.
