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.
