EP70xx family of high-performance IVRs sampling now

With its product platform, the EP70xx family, Empower has achieved the integration of a triple output DC/DC power supply with no external components into a single tiny five by five millimetre package, attaining high current density, tight accuracy during transients, and fast dynamic voltage scaling.

“Customers are excited about the game-changing nature of our technology and the impact it is having on their systems and digital ICs,” said Tim Phillips, Chief Executive Officer and Founder of Empower Semiconductor. “The combination of density, speed and efficiency is allowing designers to utilize our products in groundbreaking ways, enabling breakthrough levels of system performance.”

Empower Semi’s patented digitally configurable hardware platform has simplified the adoption of DC/DC converters for designers.  With a single footprint, no external components, extensive programmability, a wide range of current and output configurations, power designers can proliferate the EP70xx across nearly all designs and platforms. By having multiple entire power supplies in a single IC package, the company aims for the usual concerns of component variation and sourcing, synchronisation and stability to be all either eliminated or reduced significantly.

“Empower Semiconductor had a vision to not only offer breakthrough performance and density, but to make the design process simple with high confidence.  We made it simple to place the EP70xx on the PCB with no discrete components, select your settings using the provided GUI, and load the device via the I3C/I2C port.  Just like that you have three outputs regulating at high currents with wide bandwidth and high efficiency,” explained Trey Roessig, Chief Technology Officer & SVP of Engineering of Empower Semiconductor. “No input filter design, no output filter design, no feedback resistors, no loop compensation design, no component changes.”

The EP70xx family displays peak efficiencies of up to 91% with a nearly flat efficiency curve up through ten amps of output current due to its unique architecture. The devices showcase 1,000x faster dynamic voltage scaling than competing products, enabling fast and lossless processor state changes that can save 30% or more of processor power.

EP70xx family comes to market with eight initial products: four triples, two duals and two singles. Outputs are available from one to ten amps in a 5x5 or 4x4mm package with a 0.75mm profile, which is three to five times thinner than traditional integrated power modules and inductors. The products achieve 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 the SoC.
