PRESS RELEASE
Gen2 SupIRBuck Family
The second generation of SupIRBuck family of
integrated point-of-load (POL) voltage regulators
features IRs latest advantages in control IC,
MOSFETs and package integration technologies to
deliver up to 12A output current in a
low-profile, thermally enhanced 5x6 mm Power-QFN
package. The four Gen2 devices, IR3831MTRPbF,
IR3840MTRPbF, IR3841MTRPbF and IR3842MTRPbF are
fully featured for server, storage, Netcom and
telecom applications and are designed to offer
benchmark efficiency over the entire load range
and a very high switching frequency for
significant overall system size reduction. While
optimized for 12V input voltage, superior
efficiencies are also achieved in applications
with 9.6V, 5V or 3.3V input voltages. Moreover,
the devices common scalable footprint offer a
high level of flexibility for easy on board
implementation.

• Thermal Protection
• Enable pin with Voltage monitoring capability
• Power Good output
• -40?C to 125?C operating temperature

• Advantages
• These devices offer benchmark efficiency over the
  entire load range of above 96 peak efficiency,
  resulting in energy saving and very simple
  thermal management
• The ability to operate at very high switching
  frequency and the small footprint allows reducing
  the solution size making these devices ideal for
  space constrained applications.
• The excellent package thermal properties and low
  height allow back-side mounting for additional
  space saving
• High programmability and a common footprint for
  4A, 8A and 12A modules make these devices very
  flexible for easy implementation along with a
  faster time-to-market.
• These devices are optimized for 12V input voltage
  and eliminate the need for traditional dual stage
  POL conversion, thus saving energy, size and
  cost by operating directly from 12VIN.
