Description

The MCP19110 is a mid-voltage (4.5-32V) analog-based PWM controller with an integrated 8-bit PIC(R) 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. Please Note: Our MCP19110 is a smaller, functionally equivalent version of our MCP19111. The MCP19111 development tools, including both hardware and software tools, provide a convenient and powerful development platform upon which to develop and evaluate your power supply design.
