The TPS61199NSR from Texas Instruments is a highly integrated white LED driver IC designed for LCD monitor backlighting applications. It features a current-mode boost controller and eight current sinks, capable of driving up to eight LED strings in parallel. Each string offers independent current regulation with 3% current matching accuracy between strings.
This device supports an input voltage range of 8V to 30V and can deliver an output voltage up to 60V. It provides a maximum LED current of 70mA per channel and operates with a switching frequency between 500kHz and 800kHz. The TPS61199NSR includes PWM control for brightness dimming, achieving ratios up to 5000:1 at 200Hz. It also integrates essential protection features such as MOSFET over-current protection, programmable LED short protection, adjustable LED open protection, and thermal shutdown protection.
The TPS61199NSR is available in a 20-pin SOIC package with surface mount mounting type. Its operating temperature range is -40°C to 85°C (TA). This component is suitable for monitor LCD backlight and general LED lighting applications where precise current control and dimming are required.
