Overview
The IS31FL3195-QFLS2-TR is a four-channel LED driver IC manufactured by Lumissil Microsystems. It utilizes a charge pump topology with programmable sequence operation and supports 1x and 1.5x modes at a switching frequency of 1MHz. The device provides an output current of 80mA per channel and operates on a supply voltage range of 2.7V to 5.5V. It features a shutdown current of 1uA and is housed in a 16-WLCSP package measuring 1.88x2.08mm. The component is rated for an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates a charge pump topology supporting 1x and 1.5x conversion modes for efficient LED driving.
- Features programmable sequence operation allowing customized lighting patterns without external microcontrollers.
- Provides high output current capability of 80mA per channel for bright LED illumination.
- Includes ultra-low power shutdown mode with 1uA consumption to extend battery life.
Applications
- Automotive interior ambient lighting systems
- Smart home decorative and accent lighting
- Consumer electronics status indicators
Procurement Notes
Verify the specific suffix QFLS2 against the official Lumissil datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the 16-WLCSP (1.88x2.08mm) form factor. Confirm that the design accounts for the thermal requirements associated with 80mA per channel operation within the specified temperature range.
Selection Notes
Select this component when a compact solution is required for multi-color or multi-zone LED control in space-constrained designs. The integrated charge pump eliminates the need for external inductors, simplifying the bill of materials. The programmable sequence feature is advantageous for applications requiring dynamic lighting effects without complex firmware overhead.
Part Context
This part belongs to the IS31FL3195 series from Lumissil Microsystems, designed specifically for RGBW LED applications. It is distinct from linear drivers like the IS31FL3196 due to its charge pump architecture, which allows for higher efficiency and different voltage handling capabilities suitable for automotive and consumer environments.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Lumissil Microsystems directly for qualified alternatives or cross-reference options based on specific electrical and mechanical constraints.
