Linear Technology Corporation announces power management solutions for the Altera® Arria® 10 FPGA Development Kit. Technical details of this board can be found at linear.com/altera. Linear Technology’s solutions address key power requirements of the Arria 10 FPGA Development Kit and its supporting system blocks. For example, the LTC3877 VID Controller plus LTC3874 Phase Extender DC/DC Regulator provide 105A at 0.95V for the core rail from a 12V input. To complement the power saving advantages of the Arria 10 FPGA, this solution provides two key advantages:
- 6-bit parallel VID that interfaces directly with the Arria 10’s SmartVID to reduce the FPGA’s static and dynamic power consumption
- Ultralow value and temperature compensated DCR load current sensing, which maximize the efficiency and load current precision
Powering the high speed transceivers is Linear Technology’s 20A µModule® regulator (LTM4637), which provides the simplest and quickest solution by integrating a shielded inductor, MOSFETs and DC/DC regulator into a small 15mm x 15mm LGA or BGA package.
