According to the Darnell Group, a leading power management market research firm, the global communications power market is expected to grow from $4.4 billion in 2003 to $5.8 billion in 2008, a compound annual growth rate (CAGR) of 5.5%.
In units, the market is expected to experience a CAGR of 11.2% during the same period.
Currently, communications ASICs deploy deep submicron technologies that require a sub-2V power source at high current.
At the same time, power demand is increasing along with the number of the ports per board and speed of communication.
National Semiconductor simplifies power conversion from the high-voltage bus to the low voltages required in communications and automotive equipment.
"Coilcraft is proud to collaborate with National Semiconductor by providing magnetics to support National's innovative LM5000 and LM5030 high-voltage power solutions for use in high density DC/DC controllers", said Paul Liebman, Vice President of Marketing at Coilcraft.
"The two companies look forward to offering quality products and services to this rapidly growing segment of the power management market".
As an industry leader in power management, National Semiconductor's high-voltage power IC portfolio also includes the LM5041/LM5100 100V cascaded controller-driver chipset with programming timing.
National has developed power management technology for a wide range of applications including communication infrastructure, wireless handsets and other portable devices, servers and PCs.
National's LM5000 is a fully integrated, current-mode, pulsewidth modulation (PWM) DC/DC regulator that operates with a wide range of input voltage between 3.1 and 40V.
A built-in 80V power DMOS transistor is rated up to 2A peak with a channel resistance of 200mohm.
The versatile LM5000 operates at user-selectable frequencies up to 1.25MHz.
The LM5000 offers high-density, high-efficiency power conversion solutions in telecommunications, automotive, networking, industrial, and battery-powered applications.
The world's first 100V, high-frequency current-mode DC/DC controller, the LM5030 is a PWM controller with all the features to implement state-of-the-art push-pull and bridge topologies.
Ideal for powering communications equipment such as central office switches, DSL access multiplexers, high-availability systems and 48V distributed power systems, the LM5030 integrates an internal 100 V startup regulator in a thermally enhanced chip-scale package.
National's LM5000 family is designed using the company's newest high-voltage (100V) analogue bipolar-CMOS-DMOS process (ABCD150-HV), which enables integration of logic circuitry, regulation functions, precision analogue circuits, drivers and power switches on a single die.
This family also makes good use of National's advanced packaging initiative to produce the world's smallest 100V power devices in a thermally enhanced, surface mount, leadless leadframe package (LLP).
The LM5000 fully integrated high-voltage switching regulator in an TSSOP-16 or LLP-14 package is priced at $2.00 each in 1000 quantities.
The LM5030 high-voltage PWM controller in an MSOP-10 or LLP-10 package is priced at $1.85 each in 1000 quantities.
The LM5030 and LM5000 are available for sampling now with volume production in May and June, respectively.
