The Texas Instruments TPS61187RTJR is a White-LED driver designed for notebook applications, featuring a PWM interface and an Auto Phase Shift function. This device operates with an input voltage range of 4.5 V to 24 V and can provide an output voltage up to 40 V. It supports six channels, each capable of delivering up to 30 mA of LED current.
The TPS61187RTJR boasts a programmable switching frequency ranging from 300 kHz to 1 MHz, with a maximum duty cycle of 94%. It offers a peak efficiency of 94% and utilizes a Boost topology. The device includes features such as load disconnect during shutdown, integrated loop compensation, and six current sinks. It supports wide PWM dimming frequency ranges, from 100 Hz to 50 kHz for Direct PWM Mode, and 100 Hz to 22 kHz for Frequency Programmable Mode, providing dimming ratios up to 10000:1.
Packaged in a 20-WFQFN exposed pad (4x4 mm), the TPS61187RTJR is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C. The integrated 2-A, 40-V MOSFET and small external components simplify design. Additional features include programmable overvoltage threshold, built-in WLED open/short protection, and thermal shutdown.
