SUB2r, a self-funded startup makes a video camera for storytellers and gamers who want to create compelling video content. The company had a problem: visible current noise was marring the images coming from its eponymous video camera. The SUB2r camera is really a video computing platform with a configurable, customizable, upgradeable, programmable, open-architecture imaging pipeline based on an FPGA-based implementation. The camera derives its operating power from the attached USB 3.0 cable, which limits the camera’s power supply input to 5 volts at 3 amps. The camera’s original, internal voltage down-converter design was injecting a significant amount of noise into the circuitry, which resulted in a noisy image.
The SUB2r customizable video camera gets its video pipeline programmability and configurability from an FPGA that’s powered by four Intel® Enpirion® Power Systems on Chip (PowerSoC) modules.
SUB2r called in an expert power-conversion team from Intel for help. The team helped SUB2r redesign the camera’s on-board voltage regulation using four Intel® Enpirion® Power System on a Chip (PowerSoC) devices: the EN5319QI, EN5329QI, EN5339QI, and EN6340QI PowerSoCs. These four Intel Enpirion PowerSoC modules generate the four on-board power supplies required by the FPGA:
- 1 volt at 3 amps
- 5 volts at 3 amps
- 8 volts at 1 amp
- 5 volts at 2 amps
After the power supply was redesigned using the Intel Enpirion PowerSoCs, visible current noise in the camera’s video output stream became undetectable. As a bonus, current consumption drawn over the USB 3.0 power/data cable dropped from 3 amps to 1.6 amps and the passively cooled camera’s internal operating temperature dropped from 58° C to 41° C due to the improved power supply efficiency. The reduced internal operating temperature should improve camera reliability, as it would in any electronic system – like yours.
The design team at SUB2r was so impressed by the overall result that they made a short “thank you” video for the Intel Enpirion team that helped with the redesign. You’ll find that video here.
If you are facing tough power-conversion challenges, think about the results that SUB2r achieved and then consider giving the Intel Enpirion team a call. They’re here to help.
