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

Aug 2, 2010

August 2, 2010 - National Semiconductor Corp. (NYSE:NSM) today 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 junction temperature range of -55 degrees C to +125 degrees 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 junction temperature range down to -55 degrees C
  • 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 percent
  • Small 10.16 mm by 13.77 mm by 4.57 mm package (RoHS compliant)
  • Low radiated emissions (EMI) complies with EN55022 class B standard
  • Passes 10V/m radiated immunity EMI test standard EN61000 4-3
