Enpirion's 12-V integrated power IC claims to deliver the industry's highest power density

May 21, 2012 // By Paul Buckley
Enpirion has introduced the EN2300 family of fully integrated 12 Volt DC-DC converters, implemented in the company’s industry leading power MOSFET technology which the company claims offers double the power density compared with alternative solutions.

The addition of the EN2340QI 4 Amp, EN2360QI 6 Amp, EN2390QI 9 Amp, and EN23F0QI 15 Amp devices further broadens Enpirion’s extensive PowerSoC (power-system-on-chip) portfolio. The 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. Enpirion says the company’s customers have already validated the benefits of the devices 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,” said 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 4 Amp at 190mm 2 to 15 Amp at 308mm2 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 14 V and an output voltage range of 0.6 to 5 V.

Tthe EN2300 DC-DC converters and the broader Enpirion PowerSoC portfolio address a number of telecommunication, enterprise, industrial embedded, and storage applications, which include:

Highest power density

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
