Easy-to-Use Modules Accelerate Time-to-Market, Deliver Superior
Thermal and EMI Performance SANTA CLARA, Calif., Jan. 25
/PRNewswire-FirstCall/ -- National Semiconductor Corp. (NYSE:NSM)
today introduced the first three products in its SIMPLE SWITCHER®
power module family. The LMZ-series of power modules provide an
innovative, integrated solution that will save design time and
provide ease-of-use to help system designers get their products to
market faster. The 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. Other
devices in the SIMPLE SWITCHER power module family will launch
throughout 2010. National's power modules simplify power supply
design for field-programmable gate arrays (FPGAs), microprocessors,
digital signal processors (DSPs) and other point of load (POL)
conversions for medical, broadcast video, communications,
industrial and military applications. Its patent-pending packaging
technology provides low radiated electromagnetic interference
(EMI), enabling National's power modules to meet the requirements
of the EN55022 (CISPR22) Class B radiated emission standard. The
modules' efficient heat dissipation and large exposed-bottom pad
allows for operation in high-ambient temperatures without the need
for airflow. They typically operate as much as 10 degrees cooler
than comparable modules. Additionally, the power modules' single
exposed-bottom pad allows for easy and quick prototyping on lab
benches, eliminating the possibility of non-visual solder bridging.
The size and lead pitch of these modules enable the use of the same
pick-and-place manufacturing employed with standard TO-263
packages. Each module is pin-to-pin compatible with other family
members, allowing designers to create one layout to facilitate
last-minute drop-in replacements if load current requirements
change. Power supply designers can design with SIMPLE SWITCHER
power modules using National's award-winning WEBENCH® Power
Designer, as well as the new WEBENCH Power Architect design tool.
The enhanced WEBENCH Power Architect enables engineers to rapidly
create multi-output DC-DC power supplies for an entire system.
Technical Features - SIMPLE SWITCHER Power Modules National's
SIMPLE SWITCHER power modules provide -40 degrees C to 125 degrees
C operation, along with low output voltage ripple and a wide
voltage and current range that enable a complete customer-specific
power supply solution. The first release of the LMZ power modules
supports the common 3.3V, 5V, 12V and 24V input voltage rails and
offers load currents up to 4A. Available in 7-lead, 10.16 mm by
13.77 mm by 4.57 mm packages, the LMZ-series feature best-in-class
thermal resistance (theta-JA) temperature of 20 degrees C per watt.
The LMZ10504 supports maximum load currents of 4A with an input
voltage range of 2.95V to 5.5V. For more information on the
LMZ10504 or to order samples and an evaluation board, visit
