Description
AI
The MCP19119 is a mid-voltage (4.5-40V) analog-based PWM controller family with an integrated 8-bit PIC® Microcontroller. This unique product combines the performance of a high-speed analog solution, including high-efficiency and fast transient response, with the configurability and communication interface of a digital solution. Combining these solution types creates a new family of devices that maximizes the strengths of each technology to create a more cost-effective, configurable, high-performance power conversion solution. The MCP1911x family, when combined with Microchip's MCP87xxx MOSFETs, or any low-FOM MOSFET, produce high-efficiency (>96%) DC/DC power-conversion solutions. Note that the MCP19119 is an enhanced version of the MCP19111, and the MCP19111 design tools can be used with the MCP19119 (design analyzer, evaluation board, user guides, and application notes).
