TPS61185RGER Description

Short technical summary and product information.

The Texas Instruments TPS61185RGER is an active WLED driver IC with a PWM control interface, suitable for notebook LCD display backlights. It features 8 output channels, each capable of delivering 25mA of LED current.

 

The device operates within an input voltage range of 4.2V to 24V and can provide an output voltage up to 40V. It utilizes a Boost topology and offers a programmable switching frequency from 600 kHz to 2 MHz, with a maximum duty cycle of 94%. The TPS61185RGER includes features such as load disconnect during shutdown, integrated loop compensation, and adaptive boost output for optimal efficiency.

 

Designed for ease of use, it allows for small L-C component selection. The driver supports PWM brightness control with a programmable dimming frequency range of 100 Hz to 5 kHz, and up to 20 kHz direct PWM dimming. It also incorporates protections like WLED open/short protection and over-temperature protection.

 

The TPS61185RGER is housed in a 24-VQFN (4x4 mm) package, designed for surface mounting.
