5v to ≈70v dc-dc converter in the 1w range?

Click For Summary

Discussion Overview

The discussion centers around the search for a 5V to approximately 70V DC-DC converter in the 1W range, specifically for use in a bio stimulation device. Participants explore the technical requirements and challenges of sourcing components suitable for this application, including considerations of safety standards and the nature of the electrical system involved.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant expresses uncertainty about finding a suitable DC-DC converter or transformer for their bio stimulation device, highlighting the challenge of translating theoretical requirements into market-available components.
  • Another participant questions the intended use of the bio stimulation device, asking for clarification on its application and the source of the 5V input.
  • A participant mentions having a 5V, 0.2A pulse system and discusses the possibility of using an AC system that alternates between 0 and 5V, while expressing concerns about the complexity and cost of finding a suitable DC-DC converter IC.
  • There is a reference to UL544 and its importance, although details about its relevance are not fully explored in the discussion.
  • One participant suggests that the original poster should study Biomedical Engineering or consider hiring a licensed professional engineer with relevant experience, indicating a concern for safety and expertise in the project.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best approach to sourcing the necessary components or the specifics of the bio stimulation device's application. Multiple viewpoints and uncertainties remain regarding the technical requirements and safety considerations.

Contextual Notes

There are limitations in the discussion regarding the assumptions about the electrical system's design, the specific safety standards applicable, and the feasibility of the proposed solutions. The discussion does not resolve these issues.

Who May Find This Useful

This discussion may be of interest to individuals involved in biomedical engineering, electrical engineering, or those developing medical devices, particularly in the context of bio stimulation technologies.

I am looking to find a 5v to ≈70v dc-dc converter in the 1w range or the equivalent transformer + diodes. This is for a bio stimulation device and I need a high voltage and low amperage. However, not having spent years researching and buying electrical components, I'm a little uncertain where to look and for what exactly to look for. The requirements are fairly straight forward but turning theory into something that is actually on the market is difficult without having been in the industry for a while. Thanks.

Talk to me about UL544. What is it? Why is it important?
 
This is a biostimulation device to be used how? And for what purpose? on people? Horses? frog legs?

Where is the 5V coming from? You have 5V AC? (you need AC for a transformer)
 
I have a 5v, .2a (1w) pulse system with a 24 Hz/.7 duty cycle that originates from a dc inverter I found that meets those specifications. I know very little about transformers, I mainly know DC. Can you have an AC system that alternates between 0 and 5v instead of -5 and 5v (or whatever)? I would ideally like to just use a DC to DC voltage converter IC that has all the circuity worked out and my guess is that jury rigging something to get the voltage high and the amperage low would mess up the waveform. However, my guess is such a thing does not exist or is really expensive because it is so niche. This is just a proof of principle prototype of an electrical muscle stimulator for use on the human leg; I have a long way to go to be able to have something that will pass any kind of UL/FDA approval but I am aware if the safety concerns.
 
Please study up on Biomedical Engineering (preferably take a few local classes) before trying to do something like this. We won't be able to help you here.

EDIT -- you could also consider hiring a licensed professional EE with Biomedical experience.
