2.8Vin to 22Vin, 2A lout, 4-Switch Integrated Buck-Boost Converter with I2C Interface
Monolithic Power Systems has introduced a new synchronous, 4-switch integrated buck-boost converter, the MP8862. The converter can regulate the output voltage from a wide input voltage range of 2.8V to 22V with high efficiency. The converter supports an Iout of 2A. Vout ranges from a 1V minimum to a maximum of 20.47V with a 5mV resolution controlled through I2C. The device can operate at up to a maximum of 500kHz.
The converter’s integrated output voltage scaling and adjustable output current limit functions fit the USB Power Delivery (PD) requirement. Applications for the converter include USB PD sourcing ports and buck-boost bus supplies.
