36V / 100W Buck-Boost Converter with Low-Side MOSFETs Integrated and I2C Interface
PQ8745Q
36V / 100W Buck-Boost Converter with Low-Side MOSFETs Integrated and I2C Interface
The PQ8745Q 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 PQ8745Q operates over 3.7V to 36V wide input voltage and can output 1V to 29V voltage to support a variety of applications. The PQ8745Q 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 PQ8745Q employs current mode control scheme. The switching frequency could be set at 280kHz/420kHz/560kHz through I2C. The PQ8745Q also provides optional spread spectrum to optimize EMI performance. The PQ8745Q offers input/output over-voltage protection, cycle-by-cycle current limit, output short circuit protection, average output current limit and thermal shutdown protection. The PQ8745Q is available in 20-pin 3mm x 5mm Wettable Flank QFN packages.
