Description
General part information
TPS92543-Q1 Series
The TPS92543 device contains a synchronous BOOST controller and a monolithic synchronous buck LED driver with a wide 4.5V to 65V operating BUCK input voltage range. The TPS92543 includes two sub-strings of three series connected floating bypass FET controllers.
The synchronous BOOST controller implements a peak current-mode controller to operate in constant voltage mode. The Boost can be programmed to operate as dual-phase together with another TPS92543. The output voltage can be programmed using a programmable 8-bit DAC.
The monolithic synchronous BUCK implements an adaptive on-time average current mode control and is designed to be compatible with shunt FET dimming techniques and LED matrix manager-based dynamic beam headlamps. The adaptive on-time control provides near constant switching frequency that can be set between 100kHz and 1.0MHz. Inductor current sensing and closed-loop feedback enable better than ±4% accuracy over wide input voltage, output voltage and ambient temperature range.
