Upgrade for lead-free convertors
Ericsson Power Modules is upgrading its PKD series of lead-free DC/DC convertors to lead-free assembly processes.
Ericsson Power Modules is upgrading its PKD series of lead-free DC/DC convertors to lead-free assembly processes The first of the new convertors, the PKD 4510 ASI, is available now, and has an input voltage range of 36-75V and delivers up to 15A at 3.3V

SM regulators deliver high current on the spot
The PMA family of surface mountable DC/DC regulators offers high-current outputs from 1.2 to 5V.
Quarter bricks have minimum environmental impact
Combining competitive pricing with excellent performance and reliability, Ericsson Power Modules' PKM-E quarter bricks are designed to offer minimum environmental impact to meet future legislation.
It offers a power increase of 88% over its predecessor in the same package and at a competitive price.
The new family of onboard DC/DC convertors will eventually include 1V/20A, 1.2V/20A, 1.5V/20A, 1.8V/20A, 2.5V/15A and 5V/10A versions.
These will be introduced throughout 2003.
The single-output PKD DC/DC convertors were the world's first surface mount DC/DC convertors designed for lead-free manufacturing processes, and can withstand reflow soldering at temperatures up to 260C.
The performance increase in the new versions has been achieved through better use of the ceramic substrate and thermal design improvements, including better thermal and electrical conductivity in the lead-frame material.
New mosfet technology has reduced power losses and resulted in increased efficiency, now typically 90-91% at full load.
Price competitiveness has been ensured through greater integration of synchronous rectification control functions in a new ASIC and improved automated production processes.
Another new feature of the enhanced product family is both negative and positive remote control functions in each module, providing more design flexibility for users.
PKD DC/DC convertors are 7.5mm high, allowing close spacing, down to 15mm, of printed circuits boards to minimise system size.
They have a footprint of 46 x 50mm and weigh less than 22g.
No heatsink is required and the lead-frame design ensures reliable connection to the printed circuit board and operation over a wide temperature range.
Designed to meet current and future legislation with respect to lead-free manufacturing, PKD DC/DC convertors have 1500V DC input/output isolation and the typical mean time between failures is expected to reach similarly high levels to those of their predecessor (5.1Mh at +75C).
They are ideal for distributed power architectures in a wide range of telecomms and datacomms applications.
The PKD 4510 ASI is available now and priced at $39 each in 1000-off quantities.
