Microchip Technology, Inc. PMIC - PMIC - Voltage Regulators - DCDC Switching Controllers - MCP19111-E/MQ MCP19111-E/MQ

The MCP19111-E/MQ is a digitally-enhanced power analog controller designed for synchronous buck applications. It operates with an input voltage range of 4.5V to 32V and can output voltages from 0.5V to 3.6V, with higher outputs requiring an external divider. The device features a switching frequency adjustable from 100 kHz to 1.6 MHz and has a typical quiescent current of 5 mA. This controller supports high-drive capabilities with a +5V gate drive, providing source and sink currents of 1A/2A for high-drive and 2A/4A for low-drive configurations. It includes peak current mode control, differential remote output sensing, and is suitable for multi-phase and multiple output systems, functioning as either a master or slave. Configurable parameters include overcurrent limit, undervoltage lockout, and soft start profiles, among others. The MCP19111-E/MQ is AEC-Q100 qualified, making it suitable for automotive applications. It comes in a 28-lead QFN package and features an integrated 10-bit ADC with multiple internal and external channels, as well as various timers and I2C communication capabilities. This product is ideal for engineers looking for a versatile and configurable DC-DC controller for their projects.
