National Semiconductor Adds Nine Extended Temperature Products to SIMPLE SWITCHER Power Module Family
National Semiconductor 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 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
The LMZ10503/4/5EXT power modules support maximum load currents of 5A with an input voltage range of 2.95V to 5.5V. For more information or to order samples and an evaluation board, visit:
