12 Volt fully integrated DC-DC converter from Enpirion for high density applications

Enpirion has announced the availability of the EN2300 family of fully integrated 12 Volt DC-DC converters. The addition of the EN2340QI 4 Amp, EN2360QI 6 Amp, EN2390QI 9 Amp, and EN23F0QI 15 Amp devices broadens Enpirion's PowerSoC (power-system-on-chip) portfolio. These devices capitalize on Enpirion's PowerSoC technology, which integrates the controller, power MOSFETs, high frequency input capacitors, compensation network and inductor. According to Enpirion, the device is built with fastest power MOSFET technology for 12V applications that outperform GaN at silicon cost levels.

Enpirion's proprietary high-speed transistor structure is implemented in 0.18u LDMOS process. "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 company says that the EN2300 devices offer compact solution footprints from 4 Amp at 190mm2 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 14V and an output voltage range of 0.6 to 5V.

The EN2300 devices are available now. The price of EN2340QI is $3.56, EN2360QI is $4.41, EN2390QI is $6.60 and EN23F0QI is $9.00 at volumes of 1k units.
