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.

The TPS92543 incorporates two sub-strings of three series connected floating bypass FET controllers to perform LED shunt FET dimming. Each controller can perform FET dimming with segment voltages of up to 55V. The device includes programmable registers for phase shift and pulse width of each individual segment.

The TPS92543 includes an internal oscillator. The UART serial interface is compatible with TPS9266x, and TPS9254x devices. The internal EEPROM can store system defaults as well as calibration and lighting module data. The four configurable MPIOs can be configured as digital inputs or outputs, or ADC input for use with system temperature compensation, LED binning and coding.

The TPS92543-Q1 is available in a 7.0mm × 7.0mm thermally-enhanced 48-pin HTQFP package with top-exposed pad.
