MCP19111 Digitally-Enhanced Power Analog Controller & MCP87XXX Family of Power MOSFETs Configurable DC/DC Analog Controller and Low Figure-of-Merit MOSFETs Combine to Form High-Efficiency Power Conversion Solutions MCP19111: Digitally Enhanced Power Analog Synchronous Buck DC/DC Controller Microchip’s Digitally-Enhanced Power Analog technology combines the power and performance of an analog-based controller with the flexibility of a digital interface. It offers 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. MCP87XXX Power MOSFET Family Microchip’s new Power MOSFETs combine with its DigitallyEnhanced Power Analog devices to form high-efficiency, and highly-flexible power conversion solutions, include point-of-load DC/DC applications. Our logic-level MOSFETs offer very attractive figure-ofmerit, including very low on-state resistance (Rds(on)) and ultra-low gate charge (Qg), available in industry standard 5 × 6 mm or 3.3 × 3.3 mm 8-pin PDFN packages.
