National Semi Adds Nine Extended Temperature Products to SIMPLE SWITCHER Power Module Family

August 01, 2010 by Jeff Shepard

National Semiconductor Corp. introduced nine new SIMPLE SWITCHER® power modules that feature an extended operating temperature range and vibration and drop testing for use in harsh environments. The ruggedized, easy-to-use LMZ10503/4/5EXT, LMZ12001/2/3EXT and LMZ14201/2/3EXT 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 wide operating temperature range of -55 to +125°C make the new SIMPLE SWITCHER power modules well-suited for field programmable gate arrays (FPGAs), microprocessors, digital signal processors (DSPs) and other point-of-load (POL) conversions in harsh environments such as industrial and military applications.

Key features for the extended temperature power modules include: extended ambient temperature range down to -55°C; vibration and drop testing for both military and industrial standards; compliant to vibration standard MIL-STD-883 Method 2007.2 Condition A and JESD22-B103B Condition 1; compliant to drop standard MIL-STD-883 Method 2002.3 Condition B and JESD22-B110 Condition B; pin-to-pin compatible with other family members; wide input voltage range up to 42V; integrated shielded inductor; efficiency greater than 90%; small 10.16 by 13.77 by 4.57 mm package (RoHS compliant); low radiated emissions (EMI) complies with EN55022 class B standard; and passes 10V/m radiated immunity EMI test standard EN61000 4-3.

National’s LMZ10503/4/5EXT, LMZ14201/2/3EXT and LMZ12001/2/3EXT power modules are available now in a 7-pin package with exposed-bottom pad and range in cost from $9.50 to $17.20 in quantities of 500.
