Bangalore: Power management technology provider National Semiconductor launched the first three products in its 'Simple Switcher' power module family. According to the company, the LMZ-series of power modules provide an integrated solution that will save design time and provide ease-of-use to help system designers get their products to market faster.
"The power modules provide the efficiency of a synchronous switching regulator with the simplicity of a linear regulator, eliminating the external inductor and complex layout placement challenges typical of switching regulator designs," says Narendra Badve, Country Manager of National Semiconductor. Available now, the LMZ10504 is priced at $7.10 each, the LMZ12003 is $7.25 each, and the LMZ14203 is $9.50 each in 500-unit quantities. Other devices in the Simple Switcher power module family will be launched during the course of the year.
National Semiconductor says that its patent-pending packaging technology provides low radiated electromagnetic interference (EMI), enabling its power modules to meet the requirements of the EN55022 (CISPR22) Class B radiated emission standard.
According to the company, the modules' heat dissipation and large exposed-bottom pad allows for operation in high-ambient temperatures without the need for airflow. It claims that these modules typically operate in as much as 10 degrees cooler than comparable modules. The modules provide -40 degrees Celsius to 125 degrees Celsius operation, along with low output voltage ripple and a wide voltage and current range that enable a customer-specific power supply solution.
With an to cut down the design time of designers, National Semiconductor has also expanded its Webench Designer tools with the introduction of Webench Power Architect, which the company says is the industry's first design tool. This tool can enable engineers to create, model and implement multiple-output, DC-DC power supplies for an entire system.
With this tool, system designers will be able to optimize multiple power supplies across several performance parameters including topology, intermediate voltage rails, footprint, efficiency, component count and bill of materials (BOM) cost. Webench Power Architect also supports the new Simple Switcher power modules. Using its library of 21,000 components from 110 manufacturers, designers have a wide range of system alternatives for creating complex systems.
