You'll be notified about news and stock updates for this project.

SourcePure is an easy-to-use, compact power supply unit that accepts a wide
array of power inputs and outputs reliable, stable 1.8, 3.3, and 5 VDC power.

Professionals and hardware hobbyists need reliable power. Whether you’re testing
a new PCB design or troubleshooting sensitive analog circuits, everything starts
with a good power supply unit. That’s why SourcePure was designed to use
precision-filtered components that won’t inject additional noise.



An included 9 V rechargeable lithium battery makes SourcePure ideal for
different situations. No matter if you need to test your board at the lab, power
your circuit in the field, or work from a library—you don’t need to carry a
heavy power supply any more!


VERIFIABLE HIGH PRECISION OUTPUT

Although it is a compact and portable power supply, SourcePure has been designed
to output 1.8 VDC, 3.3 VDC, and 5 VDC of extremely clean power. We have
validated it, and 20 pre-production units are currently in the wild with
testers. But you don’t have to believe us—take a look at the readings at each of
its outputs from our Fluke 289 TrueRMS Multimeter:

Measuring output 1.8 VDC while connected to a dynamic load:



Ultra High PSRR: 83 dB @ 100 Hz, 85 dB @ 1 KHz, 80 dB @ 10 KHz, 61 dB @ 100 KHz
(Measured at 10 mA current)

Ultra Low Noise: 9 uVRMS

Measuring 3.3 VDC output while connected to a dynamic load:



Ultra High PSRR: 60 dB @ 1 KHz, 45 dB @ 100 KHz, 30 dB @ 1 MHz (Measured at 1 A
current)

Ultra Low Noise: 30 uVRMS

Measuring 5 VDC output while connected to a dynamic load:



3 A, super high efficient switching mode power supply (switching frequency 50
kHz - 1.5 MHz)


FEATURES & SPECIFICATIONS

Supported outputs:

 * 5 VDC at 3 A: Super high-efficiency switching power supply ensures stable and
   efficient power delivery for your projects.
 * 3.3 VDC at 1 A: Experience ultra-high PSRR (Power Supply Noise Rejection
   Ratio) and ultra-low noise, perfect for precision applications.
 * 1.8 VDC at 1 A: Exceptional PSRR and minimal noise make SourcePure ideal for
   low-current, sensitive circuits.

Supported inputs: 8 VDC to 28 VDC

Main Components:

 * Texas Instruments TPS78533QWDRBRQ1
 * Texas Instruments NCP164ASN180T1G
 * STMicroelectronics LDL1117S18R

Included with each SourcePure will be a 9 V 3000 mAH rechargeable battery, a
durable aluminum case, and an assortment of useful leads seen below:

The schematics for SourcePure will be made public when crowdfunding begins.
