It has 10x high power density, 3x transient accuracy and 1000x fast dynamic voltage while enabling more power savings

The release of the EP7010 Integrated Voltage Regulator (IVR) IC by Empower Semiconductor has eased the adoption of DC-DC converters by designers. A single footprint, no external components, extensive programmability, a wide range of current and output configurations has enabled power designers to proliferate the EP70xx across nearly all designs and platforms.  By having multiple entire power supplies in a single IC package, the usual concerns of component variation and sourcing, synchronisation and stability are all either eliminated or reduced significantly.

Now the company has announced that it has enhanced the IVR to achieve fast transient response times among its power management device series.

With the revolutionary EP70xx, Empower has integrated a triple output DC-DC power supply with no external components into a single tiny 5mm x 5mm package, attaining up to 10x high power density, 3x transient accuracy and 1000x fast dynamic voltage.

System designers can leverage the EP70xx’s tight voltage regulation through an ultra-fast load transient by lowering the operating voltage of the system. The power consumption of a system is directly proportional to the operating voltage. By narrowing the window required for the voltage variation without additional components, Empower’s IVRs enable 10 per cent or more power savings and corresponding heat dissipation, resulting in a two-fold benefit of reduction in cooling costs and improved performance!

The EP70xx family displays peak efficiencies of up to 92 per cent with a nearly flat efficiency curve up through 10A of output current due to its unique architecture.  It showcases 1,000x fast dynamic voltage scaling, enabling quick and lossless processor state changes that can save 30 per cent or more of processor power.

EP70xx family is available with nine devices to choose from with up to three regulators per device. Outputs are available from 2A to 10A in a 5x5mm or 4x4mm package with a 0.75mm profile. The products provide a level of density and simplicity so high that they are also available in bumped die form for co-packaging with digital ICs, enabling full power management integration into an SoC.

“Fast start-up times can be critical in many applications and being able to offer the world’s fastest transient response times is critical to many customers. With this game-changing speed improving both energy efficiency and performance is having a tremendous impact,” said Steve Shultis, Senior Vice President WW Sales and Marketing at Empower Semiconductor. “We have achieved incredible results in our EP70XX product family that has now delivered the world’s fastest transient speeds from zero to 10A in 500ns with <15mv droop without any output capacitors. This combination of density, speed and efficiency are allowing designers to utilize our products in groundbreaking ways, enabling breakthrough levels of system performance.”

“At typical load current ramp rates, our system regulates through the event instead of just trying to catch up. This dynamic accuracy, along with our incredible DVS speeds, allows our customers to confidently drop the operating voltage in their system, providing enormous power savings in addition to the impressive board space reduction that Empower is known for,” said Trey Roessig, Chief Technology Officer & SVP of Engineering of Empower Semiconductor.

Product samples, demo boards and reference designs of the EP70xx family are available immediately from Empower Semiconductor.
