National Semiconductor adds nine extended temperature products to SIMPLE SWITCHER power module family

SANTA CLARA, USA: National Semiconductor Corp. has 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.
