PQ8741QPQ8741Q

PQ8741Q

The PQ8741Q is a buck-boost converter with two low-side integrated power switches capable of regulating the output voltage at, above, or below the input voltage. The PQ8741Q operates over 3.7V to 36V wide input voltage and can output 1V to 22V voltage to support a variety of applications. The PQ8741Q is suitable for USB power delivery application. It can work well with external USB PD controller through I2C interface and provide flexibility of programmable features. The PQ8741Q employs current mode control scheme. The switching frequency could be set at 270kHz/405kHz/540kHz through I2C. The PQ8741Q also provides optional spread spectrum to optimize EMI performance. The PQ8741Q offers output over-voltage protection, cycle-by-cycle current limit, output short circuit protection, average output current limit and thermal shutdown protection. The PQ8741Q is available in 20-pin 3mm X 5mm Wettable Flank QFN packages.
