TPS92541EVM
TPS92541-Q1 evaluation module
TPS92541EVM
Overview
The TPS92543-Q1 and TPS92541-Q1 devices implement a synchronous BOOST controller with peak current-mode controller in constant voltage (CV) mode, and a monolithic synchronous buck LED driver with an adaptive on-time average current mode control. TPS92541-Q1 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 1MHz. Inductor current sensing and closed-loop feedback enables better than ±4% accuracy over wide input voltage, output voltage and ambient temperature range.
Features
- Synchronous two-phase BOOST controller with programmable output voltage up to 65V
- Two synchronous bucks with integrated switches with up to 2A continuous output current with 4% accuracy
- 6V to 60V wide input voltage range
- Six floating gate drivers for shunt-FET dimming
- BOOST and BUCK spread-spectrum for EMI mitigation
- Internal EEPROM capability
