TL are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for TL description/ordering information. The TL is an adjustable three-terminal high- voltage regulator with an output range of. V to V and a DMOS output. TL regulator is one of the favorite regulators I like apart from the usual LM family members. This fits into our topic of today – inexpensive, small size.

Hot TL – is the diode shorting the regulator? – Electrical Engineering Stack Exchange
tp783 In reply to Ron Michallick: On the top I’m using a meanwell switching supply to limit current and fine tune the output. Post as a guest Name. Tech in the Art World There’s a fine line between art and tech.
My last post is pending because I included a link I guess. You can wrap a word in square brackets to make it appear bold. I just need to get the job done. Here’s a thread you might find interesting: Since most people scan Web pages, include your best thoughts in your first paragraph.
If the regulator is so hot that it burns your hand instantly, there is likely something wrong with your implementation.
Because Vi is always higher than Vo, the diode doesn’t conduct because it is reverse biased notice that the cathode is to Vi. The data sheet even shows how to to783 it with some power transistors for higher power. I’m just trying to wrap my head around how large a transformer I would need to supply even just 1a, let alone 2a.
Vref is pretty much fixed at 1. It works well, but the T,783 regulator providing 48V gets really hot with no load attached. This will give you a mostly DC voltage with a little bit of ripple to feed the transistors. Anyways, thanks for the help. This setup is overkill for my Wh pack, but I wanted something gl783 be easy to scale up for whatever EV project I build.

It looks a bit high from here. The issues with running multiple voltage follower transistors doesn’t seem that big, nor does current limiting. The following is something I made in ltspice, and is copied directly from the datasheet. The TL might still be an option? It would certainly be MUCH smaller and more efficient, and possibly cheaper. Nov 30, 18, 9, You May Also Like: I cannot find it on any schematic in the application note and it looks like it shorts the in and out Vi to ground should be 15V but now I measure it at about V.

Where were you going to get the V DC from? If the board has minimal cooling, 0. I’ll figure out the math tomorrow and try to find a suitable transistor. Ask a new question Ask a new question Cancel.
With a V input, you get 52V across the regulator 16mA, which gives 0. Do you have a plan for getting rid of all that heat? The preceding stage to the voltage regulator could be tube or solid rectified; choke input or cap input; bridge or full wave rectified; and etc. Feb 28, 1: No doubt other variants could be sonically superior but these do provide a good alternative for cost, size and simplicity reasons.
