World’s Smallest and Fastest Voltage Regulators Sampling Now

Empower Smashes Density and Speed Benchmarks with Family of High-Performance Integrated Voltage Regulators (IVRs)

Empower Semiconductor announced the EP70xx, a cutting edge family of power management ICs that will provide significant energy savings in data centers with the single biggest point-of-load power performance disruption in over a decade.

With its revolutionary product platform, the EP70xx, Empower has achieved the total integration of a triple output DC/DC power supply with no external components into a single tiny 5mm x 5mm package, attaining up to 10x higher current density, 3x tighter accuracy during transients, and 1000x faster dynamic voltage scaling than leading competitors.

“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 usual concerns of component variation and sourcing, synchronization and stability are 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”, said 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 10A 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 1A to 10A in a 5x5mm or 4x4mm package with a 0.75mm profile, which is 3-5x 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.

Product samples, demo boards, and reference designs of the EP70xx family with input voltages varying from 2.5V to 16V are available immediately to qualified customers. Production volumes planned for Q4 2020.

New Energy Efficiency Power Technology

Businesses rely heavily on contact centers. For in-house contact centers, business owners can use a watts to amps calculator for alternating current (AC) or direct current (DC) flows to determine energy consumption. Along with determining the energy requirements, the launching of the EP70xx boosts energy savings in contact centers. 

With technology constantly evolving, methods in power management, conversion, and distribution are also changing.

Dynamic load voltages, current dissipation, and other issues don’t influence new product designs as application designers have been focused on low-cost control circuits (switching below 1 MHz frequencies) and external components. Designers also ensure that features include soft-start, filtering, stability, and load transient response optimization.

Traditional converters operate at low frequencies to attain high efficiency, involving extensively large and bulky output and input filtering. With EP70XX, large capacitors are eliminated, reducing the output voltage deviation with faster recovery times.


With small and fast voltage regulators, business contact centers attain higher efficiency. Power consumption will be lower with such new designs. The features and benefits of the latest converters promote full power management with less cost.
