Dialog Semi’s DA9062 Power-Management IC provides all of a Spartan-7 FPGA’s power requirements in less than 20x21mm. (Good for Spartan-6 FPGAs too!)

Yesterday’s blog post titled “Dialog Semi offers array of low-cost power solutions for Zynq UltraScale+ MPSoCs (and Spartan-7 FPGAs too!)” ended with this sentence:

 

 

“Note: If you’re looking for a PMIC to power your Spartan-7 FPGA design, check out Dialog Semi’s DA9062 with four buck converters and four LDOs.”

 

 

Dialog Semiconductor’s app note, AN-PM-096, titled “Power Solutions for Xilinx Spartan-7 Devices” has a full discussion of this topic and provides a reference design for the DA9062 PMIC that consumes a mere 420mm2 (20x21mm) of pcb area.

 

Here’s how the DA9062 PMIC’s four internal buck regulators and four internal LDO regulators match up to the power requirements of a Spartan-7 FPGA:

And here’s the pcb footprint for the DA9062 reference design:

As noted by Xilinx Senior Tech Marketing Manager for Analog and Power Delivery Cathal Murphy, the DA9062 PMIC makes a good match for the Xilinx Spartan-6 FPGA family as well.
