TPS61181RTER Description

Short technical summary and product information.

The Texas Instruments TPS61181RTER is a highly integrated LED driver IC designed for medium-sized LCD backlights, commonly found in notebooks. It features a built-in high-efficiency boost regulator.

 

This device supports an input voltage range from 5V to 24V and can deliver an output voltage up to 39V. It offers six channels, each capable of providing 25mA of LED current, with less than 3% current matching and accuracy. The switching frequency can reach up to 1000kHz (1MHz), and it supports PWM dimming for brightness control with a range up to 1000:1.

 

The TPS61181RTER is housed in a 16-WQFN (3x3 mm) package, suitable for surface mounting. Its operating temperature range is -40°C to 85°C. Key features include load disconnect during shutdown, over-voltage protection, and WLED open/short protection, contributing to reliable operation in display applications.
