Press Release Summary:
Designed for applications with limited board space, PTV series is comprised of 8 vertical-mount, non-isolated point-of-load (POL) dc/dc converters with efficiencies up to 94%. Units feature power conversion and control technology with Auto-Track(TM) power sequencing and pre-bias start-up capability. Taking up as little as 0.3 in.² PCB real estate, series offers current outputs of 8, 16, and 18 A and nominal input voltages of 3.3, 5, or 12 V.
Original Press Release:
Vertical Mount POL Converters Occupy Minimal Board Space and Feature Powerful Control Facilities, Including Voltage Sequencing
Modules save up to 53% board space compared to equivalent horizontal mount models
Smallest 8 A module has very compact 0.9 x 0.33 in footprint - needs less than 0.3 in² board space
FRAMINGHAM, Mass., July 21 - Artesyn Technologies (Nasdaq:ATSN) today launched eight new vertical mount non-isolated point-of-load dc-dc converters designed specifically for applications where board space is at an absolute premium. The new PTV series converters are fully compatible with POLA (Point-of-Load Alliance) standards - providing users with the flexibility and security of multiple sources of supply - and pack latest generation power conversion and control technology into exceptionally small footprint modules. The smallest model in the series - the PTV03010 - is a 3.3 Vin, 8 A output unit that takes up a mere 0.3 in² of PCB real estate.
PTV series point-of-load (POL) converters occupy significantly less board space than their PTH series horizontal mount counterparts. The PTV03020, for example, is a 3.3 Vin, 18 A output unit with a 0.6 in² footprint - less than half that of its nearest horizontal mount equivalent. As well as freeing up valuable board space, these very small dimensions make it easier for designers to place the converters next to the devices they are powering, to maximize performance.
All Artesyn PTV and PTH series POL converters feature Auto-Track(TM) power sequencing, enabling multiple converters 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. The converters also have a pre-bias start-up capability - enabling them to be used in situations where feed-through from a multi-rail device might cause a voltage to be present on the converter output during power-up.
Artesyn's PTV series POL converters offer OEMs a wealth of choice to help simplify board level design. They are available with current outputs of 8, 16 and 18 A, and with nominal input voltages of 3.3, 5 or 12 V, to suit the designer's choice of intermediate bus voltage. The converters also feature widely adjustable output voltages, enabling them to satisfy virtually all the supply requirements of low voltage silicon. The 3.3 V input PTV030xx's can have their outputs set to any voltage from 0.8 Vdc to 2.5 Vdc; the 5V input PTV050xx's have a 0.8-3.6 Vdc output range; and the 12V input PTV120xx's have a 1.2-5.5 Vdc output range. The 12V input PTV050xx's are also available with a 0.8-1.2 Vdc output range, for use with very low voltage silicon.
The 12 V input models are ideal for use within intermediate bus architecture (IBA) applications where higher power solutions are required, and are compatible with Artesyn's recently released IBC25A 300 W eighth-brick intermediate bus converters. Furthermore, the POL converters' sequencing capabilities mean that designers can now implement complex distributed power schemes without having to use multiple isolated bricks or external circuitry to provide the sequencing functions, thereby achieving significant savings in development time and cost.
The PTV series comprises two categories of non-isolated POL converters - determined primarily by output current capability and physical size - each of which contains a number of models covering the nominal input voltage values of 3.3, 5 and 12 V. PTVxx010 converters measure just 0.90 x 0.33 inches (22.9 x 8.4 mm), have an installed height of 0.4 in (10.2 mm) and are capable of providing up to 8 A output current, with conversion efficiencies as high as 94%. The higher power PTVxx020 converters measure 1.75 x 0.37 inches (44.4 x 9.4 mm), have a height of 0.5 in (12.7 mm) and include models with an 18 A output capability.
Artesyn's PTV series POL converters are fully interoperable with similar products manufactured by other members of the Point-of-Load Alliance, providing considerable sourcing flexibility, long-term security of supply and support for very high volume applications. The converters carry a full set of international safety approvals, including EN60950 (TÃœV Product Service) and UL/cUL60950, and have an operating ambient temperature range of -40 to +85 degrees Celsius.
Pricing for 10,000-piece quantities starts at US$6.50 for the PTV03010WAH, which is an 8 A POL converter, rising only to US$11.00 for the PTV05020WAH POL converter, which has an 18 A output capability. The standard lead-time is stock to 6-8 weeks.
Background: The Point-of-Load Alliance (POLA) was formed by Artesyn, Texas Instruments and Astec Power of Emerson Network Power in June 2003. Ericsson Power Modules and Murata are also now members. The alliance's aim is to standardize leading technology for high performance POL converters, ensuring interoperability and customer design flexibility. Under the terms of this alliance, all four companies are developing POL converters that have the same functionality, pin-outs and form factors. The advantages for customers include flexibility of sourcing and security of supply. For more information about Artesyn's POLA products, see http://artesyn.com/powergroup/new_pola_pth_launch.htm
