MICROCHIP TECHNOLOGY IC: driver; buck-boost; AFE,LDO; I2C; VQFN32; Ch: 4; 4.5÷36VDC [MCP19061T-E/RTB]
The Microchip 4 switch buck-boost controller features a digital PWM controller with a serial communication bus for external programmability and reporting. Various enhancements were added to the MCP19061 to provide USB-PD compatibility with minimum external components along with improving calibration, increasing accuracy and providing greater flexibility. Complete customization of device operating parameters, start-up or shutdown profiles, protection levels and fault handling procedures are accomplished by internal digital registers. Adjustable output range 3V to 36V Internal LDOs and MOSFET drivers High accuracy internal divider to set full range output voltage without external resistors Accuracy of input and output voltage measurement 2% from device to device over output voltage range and temperature Accuracy of output current measurement 3% from device to device over output voltage range and temperature
