I believe that these high density layered ceramic caps are failure prone. Having an external cap means you can choose the largest cap that works in a specified footprint
5V go in, whatever you want that's less than 5V comes out. It's a buck converter liek the LM2596, but smaller and with somewhat narrower operating conditions
From what i understood, it also has the inductor already in the package, and use some sort of ferromagnetic epoxy for the package to shield the inductor. This means you could build a vrey tiny 6A buck converter that only needs some capacitors and resistors next to the chip. As you may have seen from the pictures of its footprint, this is more interesting for industrial use, rather than hobbyists, simply because it would be very hard to solder by hand.
The inductor is integrated. From a quick glance at the Datasheet you really only need a single resistor to set the voltage THO it is recommended that you use input and output caps. There is also an input resistor but I dont know what thats about
@@Novus_Ordo_Conditor Wouldn't they simply pour the epoxy into a small mold/cavity containing the core, and let it harden? That's my guess. Perhaps you meant something else?
@@dieselphiend Dude, ferrite cores cannot be mold like epoxy, ferrite cores are made by pressing under high pressure, I mean; how did they put a previously produced hard object into the epoxy body or is there really a ferrite core inside?
Hey TI help me make a Lithium Polymer battery charger balancer for my 6kw diesel powered micro turbine genset for UAS and UGVs. Need to step down 140-350vdc to 50vdc @ 6kw keeping it small as possible. 😂
If you can regulate the upstream higher voltage by actively controlling your generator as a motor in regenerative braking mode. Then you could use something like 3-4x of the vicore 400v to 48v 1.75kw BCM modules. BCM6123TD1E5135yzz being a specific part number. Then the battery bms is just a normal bms.
give us a datasheet and price/availability.
Power, Power, Power! Module, Module, Module! Maximum, Maximum, Maximum!
Good thing capacitors are not included.
2025: .... smart inductors with.... AI
Why is it a good thing? (Trying to learn)

@@autonomousperson thanks!
I'm only an electronics and RF enthusiast so I'm not sure exactly what these are used for. Anyone? What goes in, and what comes out?

Something says that they don't have a good band image/management team.
Is the inductor included in the chip body an air-core inductor or is something with magnetic properties used as a core? Like ferrite?

It definitely is a ferrite core. Otherwise they would not be able to get acceptable inductance/saturation currents
@@mimimimmmim I wonder how they put such a structure inside an epoxy body? Very interesting.

a new package, wow...
Amazing!!
No quiescent current in the datasheet, but efficiency reaches 50% at 100mA... on a 5V to 3.3V converter??
The link is just a description paper. The actual datasheet for for example the TPSM82866A does have quiescent currents of around 12µA
@@AlpineTheHusky Thanks, that's a better advertisement than watever this is

How many watts you need? I see something in the 600 watt range. I've been looking for something similar for a high voltage drone tether.
@@dieselphiend - he listed 6KW, so ten times that
@@stevebabiak6997 I must have been baked.

This is so cool.
30 seconds of useless introduction...
Whats next? Integrated capacitors? Integrated transformers? Just plug it into mains.
Well the input ranges is well not that amazing. Still need a DC-DC for anything in a car even medical applications will need a extra chip.
Its more so designed for compute supplies as they need insane density in many cases.
