Description
Replacement Regulator for the Virtual Boy
04/14/2021 - Untested - Updated design to use the Power Good pin of the regulator instead of a RC delay, and measured the PG signal of original regulator.
10/15/2020 - Untested - New Switching Regulator Design.
Drop in design for simplicity.
Cost Breakdown:
- LCSC Parts Price ~$7 USD + Ship
- JLCPCB PCB Price ~$4 USD + Ship
Stock PCB is approx 17.75mm x 13.75mm, and this replacement is 17.78mm x 14.61mm so their wont be any clearance issues.
Details of stock input power:
- 10v DC @ 850ma from Stock Power Adapter (SNES Adapter)
- 9v from 6x AA Batteries.
Regulator Details:
- Input: 7v-17v DC
- Output: 5v DC @ 1.5A Peak
- Efficiency: @9-10v input, output load of 125mA - 1.5A the regulator IC provides ~90% efficiency. (Less any component losses)
- Based on the Texas Instruments - TPS62112 Switching Regulator.
Feel free to comment with any suggestions or if you have made on and tested it out, that would be great.
