The TPS92542 device contains a synchronous BOOST controller and a two-channel monolithic synchronous buck LED driver with a wide 4.5V to 65V operating BUCK input voltage range.

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, or three-phase together with other TPS9254x devices. The output voltage can be programmed using a programmable 8-bit DAC. The BOOST controller incorporates programmable frequency modulation technique for EMI reduction.

The monolithic synchronous BUCK implements an adaptive on-time average current mode control and is designed to generate constant voltage (CV) or constant current (CC) output. In the CC mode, the BUCK is compatible with shunt FET dimming techniques and LED matrix manager-based dynamic beam headlamps. In CV mode, the adaptive ontime control enables high bandwidth operation with fast transient response. The 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. In CC mode, the BUCK can independently modulate LED current using both analog or PWM dimming techniques.

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 five configurable MPIOs and two DIOs can be configured as digital inputs or outputs. The MPIOs can be configured as ADC inputs.

The TPS92542-Q1 is available in a 7.0mm × 7.0mm thermally-enhanced 48-pin HTQFP package with top-exposed pad.
