The MCP19111-E/MQ is a digitally enhanced power Analogue Controller with integrated synchronous driver. This is a mid-voltage (4.5 to 32V) analogue-based PWM controller family with an integrated 8-bit PIC(R) Microcontroller. This unique product combines the performance of a high-speed analogue 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. This family, when combined with Microchips MCP87xxx MOSFETs or any low-FOM MOSFET, produce high-efficiency (>96%) DC/DC power-conversion solutions.
