Hello,

I'm trying to setup the LTM4626 circuit in LTSpice based on the Demo Board DC2665A-A. As you can see the PGOOD pin is tied to INTVCC through a 100K resistor.

My LTSpice Schematic

But when I simulate the above LTSpice…

Hi team

I designed LTM4626 as the circuit attached.
However, noise occurs in the output.
Please check if there is any problem.

Hello,

I don't unterstand the how to calculate Rfset to modify operating frequency.

The datasheet gives with Rset connected between FREQ and GND :

Does it mean 274KOhm in parallel with Rfset ?

An other point is : on eval board, FREQ pin can be …

hi team

The circuit below is a circuit that uses LTspice to produce a negative voltage.

LTspice's LTM4626 has SGND and PGND.
However, the LTM4626 datasheet has one ground.
Could you tell me the pin numbers of SGND and PGND?
Because the value of pgood…

Hello,

Can I find the LTM4626 parallel model for LTpowerCAD?

I would like to use it for the design.

Thank you.

Hi

The customer face the output overvoltage issue of Enpirion EN2340. He said that the input and output were shorted and the load device was taken damage by the high voltage due to without the output overvoltage protection of EN2340.

So I'll propose LTM4622…

Hello,

I am part of a design team to build an FPGA-based circuit board. For the power supplies, we especially use some Analog devices. One of them is a LTM4626 device.
When simulating this device under LTSPICE, we observed an overshoot phenomenon as shown…

Hi all

i want to use the LTM4626 buck regulator in my design. the device drives several LDOs and one of the mode of operation is to disable most of the LDOs and keep one LDO running. so in full power the load shall be around 5[A] and in low power mode…

Hi 

Most of my customers who use umodules are interested in 3d models of umodules with complicated case shape like LTM4626, 4638, 4662. 

Is it possible to get? 

Best regards,

Dmitry.
