  High Performance Switch Mode Power Solutions
  for Altera Low Voltage FPGAs
  by Mike Shriver
  INTRODUCTION
  The core voltages for FPGAs are moving lower as a result
  of advances in the fabrication process. The newest FPGA
  family from Altera, the StratixВ® II, now requires a core
  voltage of 1.2V and the Stratix, Stratix GX, HardCopyВ®
  Stratix and CycloneTM families require a core voltage of
  1.5V. This article discusses how to power the core and I/O
  of low voltage FPGAs using the latest step-down switch
  mode controllers from Linear Technology Corporation.
  To ensure correct selection of power management circuitry,
  it is recommended to use Altera’s PowerPlay Power Estimation Tools to obtain accurate results. Tools are available
  to help determine power consumption before and during
  the design process. More information on these tools is
  available from Altera’s website: http://www.altera.com/
  support/devices/estimator/pow-powerplay.html.
  Overview
  The load and input voltage requirements for FPGA systems vary considerably. A single FPGA typically requires
  less than 2A, but for systems using multiple FPGAs, the …

  with Few External Components – Design Note 328
  Joey M. Esteves
  Introduction
  The LTC ®3414 offers a compact and efficient voltage
  regulator solution for point of load conversion in electronic systems that require low output voltages (down
  to 0.8V) from a 2.5V to 5V power bus. Internal power
  MOSFET switches, with only 67mО© on-resistance, allow
  the LTC3414 to deliver up to 4A of output current with
  efficiency as high as 94%. The LTC3414 saves space by
  operating with switching frequencies as high as 4MHz,
  enabling the use of tiny inductors and capacitors.
  The LTC3414 employs a constant frequency, currentmode architecture and can deliver up to 4A of output
  current. The switching frequency can be set between
  300kHz and 4MHz by an external resistor; alternatively,
  it can be synchronized to an external clock where each
  switching cycle begins at the falling edge of the external
  clock signal. For improved thermal management, the
  LTC3414 is offered in a 20-lead TSSOP package with
  an exposed pad to facilitate heat transfer.
  The LTC3414 can be configured for either Burst Mode®
  operation, pulse-skipping or forced continuous operation. Burst Mode operation maximizes light-load
  efп¬Ѓciency and extends battery life by reducing gate …
