Microchip Launches First Analog-Based Power Management Controller with Integrated MCU
Microchip Technology Inc. today announced its MCP19111, the world's first digitally-enhanced power analog controller, which expands Microchip's diverse range of intelligent dc-dc power-conversion solutions. Microchip also announced the expansion of its high-speed MOSFET family, with the new MCP87018, MCP87030, MCP87090 and MCP87130. The new MOSFETs are 25V-rated, 1.8 mΩ, 3 mΩ, 9 mΩ and 13 mΩ logic-level devices that are optimized specifically for switched-mode power supply (SMPS) applications.

The MCP19111 digitally-enhanced power analog controller, 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.
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.

"The MCP19111 family increases the capabilities of today's high-efficiency, analog-based power designs, enabling new levels of flexibility, optimization and integration; all in a very small footprint," said Bryan J. Liddiard, marketing vice president of Microchip's Analog & Interface Products Division. "The broad operating range and integrated, mid-voltage synchronous drivers support high-efficiency, power-dense conversion with fast, analog-based control. When combined with Microchip's newly expanded high-speed MOSFET offerings, they form fast, efficient power-conversion solutions that yield highly flexible, highly efficient power designs."
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 SMPS designers to configure and evaluate the performance of the MCP19111 for their target 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 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.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
