Key Facts:

  • Digitally enhanced power analogue controller integrates an analogue-based PWM controller with a fully functional Flash-based microcontroller
  • Combines the flexibility of a digital solution, with the speed, performance and resolution of an analogue-based controller
  • Low-cost development board includes high-speed MOSFETs
  • Expands Microchip’s portfolio of mid-voltage controller and MOSFET solutions for DC/DC power-conversion applications

Microchip announces the MCP19111, the world’s first digitally enhanced power analogue controller, which expands Microchip’s diverse range of intelligent DC/DC power-conversion solutions.  Microchip also announces the expansion of its high-speed MOSFET family, with the new MCP87018, MCP87030, MCP87090 and MCP87130.  Rated at 25V, these 1.8 m?, 3 m?, 9 m? and 13 m? logic-level MOSFETs are optimised for Switched-Mode-Power-Supply (SMPS) applications.  The combination of the MCP19111 digitally enhanced power analogue controller, a new hybrid, digital and analogue

power-management device, and the expanded MCP87XXX family of low-Figure-of-Merit (FOM) MOSFETs, supports configurable, high-efficiency DC/DC power-conversion designs for a broad array of consumer and industrial applications.

The MCP19111 digitally enhanced power analogue family operates across a wide voltage range of 4.5 to 32V and offers a significant increase in flexibility over conventional analogue-based solutions.  It offers the world’s first hybrid, mixed-signal power-management controller, integrating an analogue-based PWM controller with a fully functional Flash-based microcontroller.  This integration offers the flexibility of a digital solution, with the speed, performance and resolution of an analogue-based controller.  The MCP19111 devices support operation up to 32V, and have integrated MOSFET drivers configured for synchronous, step-down applications.  When combined with Microchip’s expanded family of high-speed MOSFETs, the MCP19111 drives customisable, high-efficiency power conversion.

The MCP19111 Evaluation Board (ADM00397), priced at $49.99, also includes Microchip’s high-speed MOSFETs and is available now.  This evaluation board is offered with standard firmware, which is user-configurable through an MPLAB® X IDE Graphical User Interface (GUI) plug-in.  The combined evaluation board, GUI and firmware allow power-supply designers to configure and evaluate the performance of the MCP19111 for their target applications.

The MCP87030/090/130/018 Power MOSFETs are available now for sampling and volume production, with the exception of the MCP87018 which has expected availability in February.  The MCP19111 controller is offered in a 5×5 mm, 28-pin QFN package.  The MCP87030 and MCP87018 MOSFETs are offered in a 5×6 mm, 8-pin PDFN package.  The MCP87090 and MCP87130 MOSFETs are offered in both a 5×6 mm, 8-pin PDFN package, as well as a 3.3×3.3 mm, 8-pin PDFN package.
