NatSemi expands 'Simple Switcher' power module family
August 02, 2010 // Christoph Hammerschmidt
National Semiconductor has introduced nine new 'Simple Switcher' power modules featuring an extended operating temperatures and vibration and drop testing for use in harsh environments. Target markets are automotive and off-highway vehicles as well as military and industrial applications.
According to the vendor, the ruggedized 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 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.
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 42 V 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 10 V/m radiated immunity EMI test standard EN61000 4-3
The LMZ10503/4/5EXT power modules support maximum load currents of 5 A with an input voltage range of 2.95 V to 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.
