Analog-based power management controller with integrated MCU

Editor’s note: I am pleased to see a solution which bridges the gap between a fully digital power controller with digital feedback control and a fully analog power controller. The void is now filled---the choice is yours as a designer.

Microchip also announced the expansion of its high-speed MOSFET family, with the new MCP87018, MCP87030, MCP87090 and MCP87130.  These are 25V-rated, 1.8 mΩ, 3 mΩ, 9 mΩ and 13 mΩ logic-level MOSFETs that are optimized specifically for Switched-Mode-Power-Supply (SMPS) applications.

The MCP19111, a new hybrid, digital and analog power-management device, in combination with 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 Analog family operates across a wide voltage range of 4.5 to 32V and offers a significant increase in flexibility over conventional analog-based solutions.  In fact, the MCP19111 offers the world’s first hybrid, mixed-signal power-management controller, integrating an analog-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 analog-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 customizable, high-efficiency power conversion.

Development Support

The MCP19111 Evaluation Board (part #ADM00397, $49.99), which also includes Microchip’s High-Speed MOSFETs, 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.

Pricing starts at $2.81 each for the MCP19111 controller, in 5,000-unit quantities. The MCP19111 controller is offered in a 5x5 mm, 28-pin QFN package. 

The MCP87030 and MCP87018 MOSFETs are offered in a 5x6 mm, 8-pin PDFN package.  The MCP87090 and MCP87130 MOSFETs are offered in both a 5x6 mm, 8-pin PDFN package, as well as a 3.3x3.3 mm, 8-pin PDFN package. Pricing starts $0.28 each for the MCP87030/090/130/018 Power MOSFETs, in 5,000-unit quantities.
