The TPS92541-Q1 is an automotive-qualified device featuring a synchronous boost controller and a monolithic synchronous buck LED driver. It operates over a wide input voltage range of 4.5V to 65V. The boost controller uses peak current-mode control for constant voltage operation and can be configured for multi-phase operation. The buck converter supports up to 2A continuous output current with 4% accuracy in both constant current (CC) and constant voltage (CV) modes. It includes integrated switches, spread-spectrum for EMI mitigation, UART serial communication (LMM compatible), and internal EEPROM for calibration and default settings.
