The Microchip Technology MCP19111T-E/MQ is a versatile DC DC switching controller with a step-down (buck) topology. It is designed to operate within a wide input voltage range of 4.5V to 32V and features a configurable switching frequency between 100kHz and 1.6MHz.
This controller supports a single output phase and functions as a transistor driver. It integrates I2C, PMBus, and SMBus serial interfaces for control and monitoring. The device is suitable for surface mount applications and comes in a 28-QFN (5x5) package.
Key electrical characteristics include its ability to handle a 4.5V to 32V input and a switching frequency up to 1.6MHz. The operating temperature range is -40°C to 125°C (TJ), making it suitable for various environmental conditions. The synchronous rectifier feature enhances efficiency in its buck configuration.
