Overview
The TPS61180RTER is a six-channel white LED driver IC manufactured by Texas Instruments, designed for notebook display backlight applications. It utilizes a boost topology to regulate current with an input voltage range of 5 V to 24 V and a maximum output voltage of 38 V. The device integrates a power MOSFET and operates at a switching frequency of 1 MHz. It supports PWM dimming and provides a regulated output current of 25 mA per channel. The component is housed in a 16-WQFN package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a high-side N-channel MOSFET for compact design
- Supports PWM dimming control for brightness adjustment
- Provides constant current regulation for multiple LED channels
Applications
- Notebook display backlight systems
- White LED driver circuits
- Portable electronic device illumination
Procurement Notes
Verify the specific suffix 'RTER' corresponds to the reel packaging configuration required for your assembly line. Confirm that the 16-WQFN footprint matches your PCB layout guidelines. Ensure compatibility with the 5 V to 24 V input supply rails present in your system design before finalizing procurement.
Selection Notes
Select this component when designing for notebook displays requiring six independent LED channels. It is suitable for systems utilizing input voltages between 5 V and 24 V. Consider the integrated MOSFET feature if minimizing external component count is a priority. Verify that the 25 mA output current meets the specific luminance requirements of the target display panel.
Part Context
This part belongs to the TPS61180 series of LED drivers from Texas Instruments. It is specifically engineered for portable computing devices. The device shares functional similarities with other members of the family but is distinguished by its specific input voltage range and output current capabilities tailored for notebook applications.
Replacement Considerations
The TPS61180RTET is a tape-and-reel variant of the same device. The TPS61180RTETG4 is a lead-free version of the component. These parts share identical electrical specifications and pinouts.
