International Rectifier Says…
iP2010/2011: First Commercially-Available GaN-based Integrated Power Stage Devices
Uses Revolutionary GaN-based Technology Platform, GaNpowIR
International Rectifier, a world leader in power management technology, introduced the industry’s first family of commercial integrated power stage products utilizing IR’s revolutionary Gallium Nitride (GaN)-based power device technology platform. The iP2010 and iP2011 family of devices is designed for multiphase and point-of-load (POL) applications including servers, routers, switches and general purpose POL DC-DC converters.
The iP2010 and iP2011 integrate a highly sophisticated, ultra fast PowIRtune driver IC matched to a multi-switch monolithic GaN-based power device. These devices are mounted in a flip chip package platform to deliver higher efficiency and more than double the switching frequency of state-of-the-art silicon-based integrated power stage devices.
“The introduction of this family of GaN-based power devices for DC-DC applications heralds a new era in high frequency, high density, highly efficient power conversion solutions, and reaffirms IR’s position at the forefront of innovative power management design,” said Goran Stojcic, executive director for IR’s POL Products, Enterprise Power Business Unit. John Lambert, POL product manager, added: “With a switching capability up to 5MHz, the iP201x family enables designers to dramatically reduce the value and size of output capacitors and inductors where space is at premium. The devices can also be configured to operate at a lower switching frequency for applications that require the highest possible efficiencies.”
EN-Genius Says…
Whenever a vendor notes something like “data sheets only available to qualified enquirers”...my nose starts to twitch.
Here we have a new process being touted by International Rectifier offering a driver together with a multi-switch power device. The input voltage range of both the 30 A iP2010 and the 20 A iP2011 is 7 V to 13.2 V while the output can be between 0.6 V and 5.5 V. There is no indication on the “Typical Application” diagram in the one page data (PD-97461) of the output being set so, presumably, there will be stock output voltages.
That diagram also does not indicate any component values at all for capacitors and the switching inductor but suggests that both positive and negative 7 V rails are required for operation?
Presumably, also, the two devices use the same die with the lower current part using different wire bonding?
The features list on the one page data exclaims “Benchmark peak and full load efficiency – no heat sink required.” But part of the release goes on to say “both devices… feature highly efficient dual-sided cooling.” That is certainly not intuitive with the photo given of the package which is, rather unfortunately called “wireless.”
Without seeing some performance curves and, especially, some charge numbers it is absolutely impossible to check the validity of these parts. The release will, no doubt, be a useful positive nudge to the investment community.
Competitors who are interested in these two parts will have already obtained copies of the data sheets. Such is the leakiness of our industry.
Both parts are sampling with demonstration boards available. The iP2010TRPbF is priced at $9.00 and the iP2011TRPbF at $6.00, both in 2500-piece lots.
Data Sheets only available to qualified enquirers.
