Microchip Technology MCP19111 Synchronous Buck DC/DC Controller

Microchip's MCP19111 Synchronous Buck DC/DC Controller combines the power and performance of a power analog-based controller with the flexibility of a digitally-enhanced interface. Offering an industry-leading level of analog-configurability, the MCP19111 integrates a configurable peak current mode analog controller, synchronous MOSFET driver, LDO, and a fully-functional PIC® Microcontroller. The integrated MCU enables a digital front-end that makes it quick and easy to configure and customize these power supply controllers to address target application needs.
