Microchip's 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. The company claims the MCP19111 is the world’s first hybrid, mixed-signal power-management controller, integrating an analog-based PWM controller with a fully functional Flash-based microcontroller. The MCP19111 devices support operation up to 32V, and have integrated MOSFET drivers configured for synchronous, step-down applications
Pricing starts at $2.81 each for the MCP19111 controller and $0.28 each for the MCP87030/090/130/018 Power MOSFETs, in 5,000-unit quantities. All are available now for sampling and volume production, except the MCP87018 with 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.
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.
