Microchip Technology Introduces dsPICDEM™ Buck Switch-Mode Power Supply (SMPS) Development Board


Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, today announced the dsPICDEM™ Buck Switch-Mode Power Supply (SMPS) Development Board (Part # DM300023), which comes with sample software and exercises to help designers quickly evaluate and develop digital SMPS and power-conversion products. The new board is populated with a dsPIC30F2020 Digital Signal Controller (DSC), and is supported by Microchip's world-class development tools, as well as a series of educational WebSeminars on digital SMPS-related topics (www.microchip.com/training).

"This new board and supporting development tools enable designers to enjoy the performance, cost, reliability and time-to-market advantages associated with digital power- conversion applications today," said Sumit Mitra, vice president of Microchip's Digital Signal Controller Division. "Microchip is pleased to partner with power-supply designers in this way, and we hope to help them achieve their goals for their next-generation power-supply products."

The dsPIC30F2020 DSC on the new board implements two of four possible independent, synchronous Buck converter circuits to allow designers to examine digital-power control techniques, as well as application performance indicators such as transient response. Onboard user potentiometers enable simulation of application features such as trim, remote-voltage sense, voltage tracking and current sharing. Additionally, a CD that includes hands-on digital power-conversion training exercises and example Buck-converter software comes with the board, to help designers quickly adapt digital power to their designs.

Designers wanting to learn more about SMPS designs and digital power-conversion can view Microchips eight online WebSeminars, on topics ranging from SMPS theory, to digital-SMPS design, to designing with the dsPIC® DSCs in SMPS and digital power-conversion applications. The WebSeminars quickly educate designers on the technical aspects of digital power conversion and SMPSs, and are hosted on Microchip's Web site at www.microchip.com/training. They are an excellent complement to the tools and resources found at Microchip's Intelligent Power Supply Design Center (www.microchip.com/power).

Development Tools
To support development using the dsPICDEM Buck SMPS Development Board, Microchip offers its high-performance MPLAB IDE Integrated Development Environment, MPLAB C30 C Compiler, SIM 30 Software Simulator, MPLAB ICD2 In-Circuit Debugger, and the recently announced MPLAB REAL ICE™ emulation system. The MPLAB IDE is available for free from Microchip's Web site at www.microchip.com/MPLAB. The MPLAB ICD2 In-Circuit Debugger, MPLAB C30 C Compiler, SIM 30 Software Simulator and MPLAB REAL ICE emulation system can all be purchased online at www.microchipdirect.com.
