Power Modules Boast Desirable Thermal and EMI Performance
National Semiconductor introduced three products in its SIMPLE SWITCHER power module family. The LMZ-Series of 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. The power modules are said to simplify power supply design for FPGAs, microprocessors, DSPs and other POL conversions for medical, broadcast video, communications, industrial and military applications. Patent-pending packaging technology is asserted to provide provides low radiated EMI, enabling the power modules to meet the requirements of the EN55022 (CISPR22) Class B radiated emission standard. The modules’ efficient heat dissipation and large exposed-bottom pad allows for operation in high-ambient temperatures without the need for airflow. They typically operate as much as 10 degrees cooler than comparable modules, according to the company.
