Enpirion Announces Family of 12V Integrated Power IC Solutions
Enpirion announced the availability of the EN2300 family of fully integrated 12V dc-dc converters, implemented in the company’s industry leading power MOSFET technology with double the power density over alternative solutions. As the leader of integrated power IC solutions, this introduction underscores Enpirion’s continued focus on miniaturizing dc-dc power systems in applications such as telecommunication, enterprise, industrial, embedded computing, and storage systems.
The addition of the EN2340QI 4A, EN2360QI 6A, EN2390QI 9A, and EN23F0QI 15A devices further broadens Enpirion’s extensive PowerSoC (power-system-on-chip) portfolio. These devices capitalize on Enpirion’s field proven PowerSoC technology, which integrates the controller, power MOSFETs, high frequency input capacitors, compensation network and inductor. The EN2300 family offers small solution sizes with uncompromised performance, highest reliability, and a 45 percent reduction in time to market. Customers have already validated these benefits with more than 50 design wins ahead of the official market release.
Enpirion’s proprietary high-speed transistor structure implemented in 0.18u LDMOS process achieves the industry’s best Figure of Merit (FOM = Gate Charge x On-state Resistance in units of milli-ohm nano-coulombs) to operate at high frequency while reducing switching losses. "Enpirion focuses on driving high speed, low-loss power MOSFET technology as the key enabler for delivering the highest efficiency solutions with leading power density," says Dr. Ashraf Lotfi, Enpirion Chief Technology Officer. "Our technology FOM of 20 provides a 40% improvement over alternative LDMOS, 73% versus VDMOS, and 33% better than high performance GaN."
The EN2300 devices offer compact solution footprints from 4A at 190mm(2) to 15A at 308mm(2) which represents up to a sixty percent area reduction versus competing alternatives at comparable performance. The devices support an input voltage range of 4.5 to 14V and an output voltage range of 0.6 to 5V.
"The broad market push towards reducing power, space, and cost while improving reliability is driving the accelerated migration from traditional dc-dc converters to integrated power-systems-in-a-package at a projected compound annual growth rate (CAGR) of 34.4% from 2011 to 2016," said Jeff Shepard, President of Darnell Group, the leading source for worldwide strategic information covering the full spectrum of power electronics.
"Enpirion’s new EN2300 family is a strong addition to the company’s already successful dc-dc PowerSoC portfolio and exemplifies the types of products we consider key in enabling this rapid growth."
The following is a summary of specific challenges in many telecommunication, enterprise, industrial embedded, and storage applications that the EN2300 dc-dc converters and the broader Enpirion PowerSoC portfolio address:
The market pressure to add more value and functionality to end products compresses available PCB space. The EN2300 family along with the rest of Enpirion’s PowerSoC portfolio provides the industry’s highest density power IC solutions -- greatly minimizing the amount of space needed for power management compared to alternative discrete and modules solutions.
All EN2300 devices achieves up to 95 percent efficiency with a flattened efficiency profile from 10% to 100% load permitting designers to manage power effectively over the entire operating range.
Enpirion integrated power IC solutions achieve 35,700 years mean time between failures (MTBF). PowerSoCs are specified, simulated, characterized, validated and manufacturing-tested as a complete power system -- which, when coupled with tightly controlled IC manufacturing processes and fewer total components, yields unsurpassed reliability.
Enpirion PowerSoCs require fewer external components. EN2300’s inherently low ripple (e.g. <10 mV) and EMI (i.e. CISPR 22 Class B compliant) eliminate the need for external noise filters, while its thermal performance eliminate the need for heat sinks or airflow.
The EN2300 family, like all Enpirion PowerSoCs, requires 45% fewer man-hours and 1/3 less exposure to design cycle iteration versus discrete switching regulators. Fully validated and proven PCB layout and design files enable customers nearly 100 percent first-pass reported success.
Enpirion’s EN2300 devices are available now. They are available with EN2340QIat $3.56, EN2360QI at $4.41, EN2390QI at $6.60, EN23F0QI at $9.00 at volumes of 1k units.
