TPS92391RHBR Description

Short technical summary and product information.

The Texas Instruments TPS92391RHBR is an active Boost/SEPIC LED driver controller IC. It is designed for applications requiring high dimming performance, such as backlighting.

 

This device features six high-precision current sinks, each capable of delivering up to 200 mA of DC current with typical 1% current matching. The input voltage operating range is from 3 V to 48 V. The switching frequency can be adjusted from 100 kHz to 2.2 MHz, with spread spectrum for reduced EMI and a sync input for external clocking.

 

Dimming capabilities include analog, I2C, and PWM control, offering a dimming ratio of up to 32,000:1 with 152-Hz LED output PWM frequency. It supports up to 16-bit LED dimming resolution via I2C or PWM input, and 12-bit analog dimming. The controller includes extensive fault diagnostics, adjustable switch frequency, soft start, and thermal shutdown protection.

 

The TPS92391RHBR is available in a 32-VQFN (5x5 mm) package and is designed for surface mount applications. Its operating temperature range is -40°C to 125°C.
