DC/DC converters claim double density

Enpirion has rolled a family of fully integrated 12V DC/DC converters with twice as much power density as alternative solutions. The EN2300 family is designed to miniaturize DC/DC power systems in telecommunications, enterprise and industrial applications, embedded computing and storage systems.

The first devices in the family are the 4A EN2340QI, 6A EN2360QI, 9A EN2390QI and the 15A EN23F0QI. The devices use the company's PowerSoC technology, which integrates the controller, power MOSFETs, high frequency input capacitors, compenzation network and inductor.

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.

The company claims the technology provides FOM that is a 40 percent improvement over alternative LDMOS, 73 percent versus VDMOS, and 33 percent better than high performance GaN.

The devices range in size from 190mm2 for the 4A EN2340QI to 308mm2 for the EN23F0QI. These sizes are said to represent up to a sixty percent area reduction versus competing alternatives. The devices support an input voltage range of 4.5V to 14V and an output voltage range of 0.6V to 5V.

Enpirion's EN2300 devices are available now. The EN2340QI are priced at $3.56, EN2360QI at $4.41, EN2390QI at $6.60, and the EN23F0QI at $9 at volumes of 1k units.
