TPS61195 Description

Short technical summary and product information.

The TPS61195 IC from Texas Instruments is a highly integrated solution for large-size LCD backlighting. This device features a boost regulator with an integrated 2.5A/50V power MOSFET, designed to efficiently drive white LEDs.

 

It offers eight current sink regulators, providing high precision current regulation and matching, capable of supporting up to a total of 96 LEDs. The input voltage range is from 4.5V to 21V, with an output voltage capability of up to 45V. The switching frequency is programmable between 600kHz and 1MHz, allowing for the use of small L-C components.

 

The TPS61195 supports multiple brightness dimming methods, including PWM and SMBus control. It provides 8-bits (256 steps) of brightness level adjustment. The device integrates protection features such as WLED open/short protection and over-thermal protection, along with programmable over-voltage threshold.

 

Packaged in a 4mm x 4mm WQFN package, the TPS61195 is suitable for surface mount applications. Its adaptive boost output optimizes efficiency by adjusting the output voltage to the WLED forward voltage. This makes it ideal for notebook and netbook LCD display backlighting.
