Industry’s highest density IVR integrates four voltage rails in miniature IC that offers industry-leading performance and extensive fault protection without external discrete components

Houston, TX, March 21st, 2022: Empower Semiconductor, Inc. the world leader in integrated voltage regulators (IVRs), has announced a series of quad-output step-down converters that combine the industry’s highest current density and efficiency, the fastest dynamic voltage scaling (DVS) and transient response, and extensive fault protection. As with previous members of Empower’s IVR family, the new digitally configurable EP71xx series can deliver complete voltage regulation and protection functionality without the need for external discrete components. Furthermore, the EP71xx series can eliminate other system components that increase cost and area by integrating those system functions.

Empower’s IVRs are high-performance power management chips designed to provide efficiency, size, and cost benefits to energy-hungry, data-intensive, electronics applications by replacing traditional power management integrated circuits (PMICs) with a single tiny IC. IVRs monolithically integrate the voltage regulator semiconductor and all the necessary discrete components into a single device. Such integration simplifies the design and implementation of voltage regulation circuitry, improves efficiency by eliminating connection losses, reduces susceptibility to EMI, minimizes the bill of materials, enhances overall reliability, and reduces PCB footprint.

The EP71xx series delivers an impressive 12A of continuous current with up to 4 voltage regulators in a single FcCSP package that measures just 5mm x 7mm and only 0.7mm in height! Maximum efficiencies can be achieved, minimizing losses across the widest possible range of operating conditions. Ultra-fast transient response supports regulation through a load step and the programmable ‘ExpressV’ DVS-on-demand is capable of up to 6mV/ns.  This feature is more than 1000x faster than other competing technologies and enables rapid, lossless, processor state changes that can significantly reduce processor power.

Commenting on the launch of the new IVR series, Mukund Krishna, Empower’s senior product marketing manager states: “Conventional power management solutions do not offer the power density, simplicity and flexibility demanded by rapidly evolving data-intensive applications. With the addition of the new quad-output devices to our IVR family, we are giving system designers the opportunity to reduce PCB power management area and components by ten times or more, drive down system power losses by as much as 50%, and greatly simplify system design.”

The new IVRs operate from a single 3.3V input and offer output current options up to 12A. The EP71xx family comprises a variety of devices that can provide the available 12A from one to four independent outputs. Output voltages are programmable from 0.5V to 2.5V and output voltage set-point accuracy is +/- 1.0%. Built-in fault protection and warning capabilities cover OVLO, UVLO, OVP, OCP and short-circuits.

The EP71XX devices pack a full suite of telemetry functionality to report voltage, current and die-temperature, and continue to feature programmable soft-start and DVS ramp rates via the digital interface. Enhancements to the EP71xx include advanced features such as user-programmable power-up/power-down sequencing, user-configurable logic levels and programmable GPIOs to enable customized system functionality. All configurations and diagnostics are available through a standard I2C interface.

Target applications for the new series will include optical transceivers, active cables, memory modules and storage devices, networking equipment such as GPON and Photonic Service Switches, PoL power for CPUs, GPUs, accelerators and AI processors and 5G systems.

Tim Phillips, CEO, president and founder of Empower, adds: “Our mission is to minimize the energy footprint of the digital economy by providing high-performance, ultra-efficient technologies that allow designers and system architects to quickly implement power management solutions that keep power consumption to a minimum. The new quad-output IVR series is further evidence of how we are delivering on that promise.”

About Empower Semiconductor

The exponential increase in the amount of data being communicated and processed around the globe is driving the energy consumption of data centers and communications networks to 17% of total electricity demand worldwide by 2030(1), dramatically increasing pollution, carbon emissions and cost.  Empower Semiconductor was founded with the mission to “minimize the energy footprint of the digital economy” by developing novel fully integrated power management solutions that both increase the performance and reduce the power consumption of energy-hungry, data-intensive applications. 

Traditional power solutions require dozens of discrete components with big footprints, complex designs and deliver power inefficiently with poor response times and inaccuracies. Empower Semiconductor’s patented IVR technology integrates dozens of components into a single IC increasing efficiency, shrinking footprints by 10x and delivering power with unprecedented simplicity, speed & accuracy and with zero discrete components. The Empower IVR™ technology solves the power density challenge to address a wide range of applications including mobile, wearables, 5G, AI, and data centers. In 2020 the capacitor technology platform was added to further address power density. E-CAP revolutionized the capacitor industry as the world’s smallest, highest performing, and incredibly reliable capacitor for wearables, mobile, and SoC applications. The company is based in Silicon Valley, CA and is led by a team of highly experienced power experts and executives.
