Overview
The TPS61181ARTET is a six-channel LED driver IC from Texas Instruments, designed for notebook display backlight applications. It utilizes a boost DC-DC converter topology with an internal switch to regulate current. The device supports PWM dimming and delivers up to 30mA per channel. It operates within a supply voltage range of 4.5V to 24V and features a switching frequency of 1MHz. The component is housed in a 16-WQFN (3x3mm) package with exposed pad and functions across a temperature range of -40°C to 85°C.
Feature Summary
- Integrates six independent regulated current outputs for multi-string LED arrays
- Supports high-resolution pulse-width modulation dimming control
- Includes an internal power switch to minimize external component count
- Provides constant current regulation for uniform backlight brightness
Applications
- Notebook display backlight systems
- Mobile device LCD backlighting
- Portable electronics requiring multi-string LED drivers
Procurement Notes
Verify the specific suffix ARTET to confirm the 30mA output current rating and 16-WQFN packaging. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm RoHS compliance status if required by project specifications. Cross-reference the manufacturer part number against official datasheets to avoid confusion with similar variants like the TPS61181RTET which has different current ratings.
Selection Notes
Select this component when designing for notebook or portable displays requiring six independent LED strings. It is suitable for systems needing precise current regulation and PWM dimming capabilities. Consider the 4.5V minimum input voltage requirement when choosing the power source. The integrated switch simplifies design compared to discrete solutions. Evaluate the 1MHz switching frequency for electromagnetic interference considerations in compact enclosures.
Part Context
This part belongs to the TPS61181 family of WLED drivers intended for notebook displays. It shares the same core architecture as other variants but differs in output current specifications and package options. The family addresses the need for efficient, space-saving backlight solutions in thin-and-light computing devices. It complements other Texas Instruments power management products for complete system integration.
Replacement Considerations
The TPS61181RTET is a related variant offering 25mA per channel instead of 30mA. Verify if the lower current rating meets the application requirements before substitution. Both parts share the same package and pinout configuration.
