Convertors adjust at the point of load
Two new high current point-of-load convertor modules provide cost-effective ready-to-use power solutions for densely populated boards.
Artesyn Technologies has launched two new high current point-of-load convertor modules that provide highly cost-effective, ready-to-use power solutions for densely populated boards Occupying a board area of just 13.8cm2, the new PTHxx040W series convertors employ an advanced topology to maximise conversion efficiency and current density - and minimise external component count - making it easy for designers to place high-current, low-voltage sources next to the silicon devices they are powering

High-efficiency, open-frame, DC/DC converters provide two independent, fully regulated, positive outputs
The PTH12040W has an output current rating of 50A, whereas the PTH04040W has an even higher 60A rating.
Both convertors offer a comprehensive set of features, including wide output voltage adjustment and auto-track power sequencing, enabling a broad diversity of applications to be satisfied with just the two models.
Artesyn's PTHxx040W series convertors are POLA compliant.

Comprehensive catalogue features wide range of new AC/DC and DC/DC products.
Fully compatible with similar products produced by other members of the Point-of-Load Alliance, they provide users with sourcing flexibility, long-term supply security and support for very high volume applications.
The convertors are primarily intended for the telecommunications and data communications markets - typical application areas include high-end blade servers, data storage switches and voice processing systems.
The 50A output PTH12040W convertor's wide 8 to 14V input voltage range makes it especially suitable for boards that utilise a loosely regulated intermediate voltage distribution bus fed by an intermediate bus convertor (IBC) or 12V AC/DC power supply.
The convertor's output can be set over the range 0.8 to 5.5V via a single resistor, accommodating virtually all the core and I/O low-voltage supply needs of latest-generation ASICs, network processors and DSPs.
The 60A output PTH04040W has an input range of 2.95 to 5.5V - ideal for boards that employ either a 3.3 or 5V distribution bus - and an output voltage range of 0.8 to 3.6V, which again is determined by a single resistor.
PTHxxx040W series convertors are packaged as open-frame modules, measuring just 52 x 26.5mm.
They are available in through-hole and surface mount configurations, and with an installed height of only 9mm are eminently suitable for systems with tight card pitches.
The convertors use an advanced multiphase topology with an equivalent switching frequency of 1.05MHz to achieve full load conversion efficiencies as high as 96%.
The 60A output PTH04040W has a power density of more than 4.8A/cm3, and both models can deliver up to 250W of useable power.
A further major advantage of the conversion topology is that fast transient output currents can be accommodated without the need for large numbers of bulky external capacitors, enabling designers to achieve significant savings in board real estate.
Both of Artesyn's PTHxxx040W series POL convertors feature auto-track power sequencing, enabling multiple convertors to track each other, or an external voltage, during power-up and power-down.
This built-in functionality provides electronics designers with a technically elegant means of powering advanced silicon devices such as DSPs, FPGAs and ASICs, which often require a number of different voltage supplies to be applied and removed in a specific, carefully controlled sequence.
PTHxxx040W series convertors also have a prebias startup capability, enabling them to be used in situations where feedthrough from a multirail device might cause a voltage to be present on the convertor output during power-up.
The convertors have no minimum load requirement, and offer differential remote sense inputs to maximise regulation.
Further facilities include remote on/off and margin up/down controls - as well as programmable undervoltage lockout to allow turn-on and turn-off voltage thresholds to be customised.
PTHxxx040W series are suitable for forced air or convection cooled environments and accommodate a wide operating ambient temperature range of -40 to +85C, with derating.
They are comprehensively protected against overtemperature and short-circuit conditions, with fully automatic recovery.
The convertors carry a full set of international safety approvals - including EN60950 (TUV Product Service) and UL/cUL60950.
In OEM quantities of 1000, Artesyn's PTHxxx040W series convertors have a unit price of US $34.50.
Standard lead-time for both models is stock to 6-8 weeks.
