Preparing a Kickstarter Campaign for NCH6300HV, the sequel of NCH6100HV

[Aiden Fang]

Dear all,

8 years ago in Aug 2012, Zeyuan Yan designed and released his first DC-DC boost converter, NCH6100HV. 

It has been so popular in the community, thanks to all supporters including (almost, if not all) everyone here in this group. It got too popular that there have been a few dozens of counterfeit products (with poor quality components) on eBay and AliExpress.

NCH6100HV is measured only at 1.77*1.46*0.7in (45*37*18mm) but is capable of powering TWELVE IN-18 tubes at once! This could have not been achieved without the premium components we picked from TDK, On Semi, SANYO, Bourns, nichicon, Vishay, Sumida etc. 

Together with the gold-plated PCB board and the carefully-thought-out layout, the NCH6100HV is capable of providing 55-60mA at 170V without voltage drop! 

With 10V-24Vdc as input, the output ranges from 85V to 235V, adjustable by tuning a pot on board. 

As a safety measure, a "shutdown" pin is provided so that the output voltage can be completely turned off when you need to, simply by pulling the "shutdown" pin to Vin or High. Both wire terminals and 0.1" pitch pins are included for more versatile applications.

Long story short, 8 years later today, it is time to update the popular NCH6100HV to a new model, NCH6300HV. 

With the suggestions from our customers over the years in mind, we made a complete redesign of this converter module, and here is a glimpse of the updated features of this brand new NCH6300HV.

* Input Voltage now starts from 3.7V (Yes to LiIon batteries!) to 15V.

* Output Voltage 100-230V, at 100mA Max!!! (@Vin=12V, Vout=170V)

* Conversion efficiency increases from 83% to whopping 92%

* 0.28"(7mm) shorter at 1.77*1.18*0.7in (45*30*18mm), compared to NCH6100HV at 1.77*1.46*0.7in (45*37*18mm)

We are preparing a Kickstarter Campaign for this coming NCH6300HV. 

This will be our first time on KS, so we would like your suggestions and comments. Pledge options, add-ons, target, anything you'd like to input. Your insights are highly appreciated.

The campaign is preliminarily planned to launch in a few weeks, by the end of October. If everything goes well, we will be able to ship these new converters in late Nov to early Dec, just in time to catch Santa's sleigh ;-)

Thank you all for your time and support! Cheers!

Warm regards,

I am in for one at least.  I will keep my eyes open for the KS.

Hello Aiden;

 

One thing that I need (or perhaps only want) is to (optionally) bring out the FB node going into the controller along with identifying the up/down resistor values so that I could apply a PWM-offset value to modify the voltage under CPU control.

Here is a fragment of the HV source I use:

 

 

The 8051 processor I use has a few PWM outputs, one that I use to generate an offset voltage to the feedback node.

 

It could be an additional (optional) pin that brings out the FB node but still allows me to plug/unplug the module.

As you can see, I would also like an enable pin, polarity optional.

 

And yes, I would be interested in the KS program.

I'm in - keep us posted please.

Thanks all for your support, to the upcoming KS campaign, as well as the continued support over the years.

Aiden is my long-time business partner in the US, and we have been collaborating seamlessly on new product developments, technical support, sales and marketing etc. Recently we have been working closely on the KS campaign of NCH6300HV, as well as making YouTube videos.

Thank you, blkadder, Bill and Richard. We will be more than happy to keep everyone posted.

Yan.

In addition, I just want to add that, the circuit of NCH6300HV was actually tested and has been used in our Omnixie Plus clocks. So the risk of potential issues will be very low ;)

[Bill Notfaded]

Great little clocks those Omnixie Plus especially the IN-18 version!  No cheap but you kinda get what you pay for with these I think.  I'm always interested in small nixie power supplies.

[Richard Arndt]

My interest however is powering single digit IN-18 clocks from USB.  The nixie only requires 1.2W typical.  Your NCH6100HV is a bit pricey and overkill for my application.  It would be nice if you could designed a low power version that is less expensive.  And yes, I do like option to measure/control/shutdown HV from micro.

Thank you BLKADDER, Bill, Richard S, Bill and Richard A. Your suggestions are well noted, and will be thoroughly considered.

Best,

Aiden
