Hi Santhosh,
I run your file and has same issue since you may change something for the file. Please download the new snvm157.zip file and follow the slide attached. You will see the simulation result.

Hope this helps…
Part Number: LMZ12001 I have a design using three of these simple switchers, and all of them have really high output ripple. For instance the 1.8V rail goes from 2.2V to 1.5V. I tried adding 100uF to the output and another 100uF to the input but that…
Part Number: LMZ12001 Tool/software: WEBENCH® Design Tools Hi,
I downloaded Altium schematic and other files using Webench CAD file export. I downloaded and trying to import to Altium, I could not extract all PCB footprints. I am getting following er…
Other Parts Discussed in Thread: LMZ12001 Using the LMZ12001 with a 12Vin and 1.2V output and 250uF output capacitance has a slow current step response. Going from about 30mA to 200mA-250mA takes about 40ms to adjust back into regulation. I believe that…
Part Number: LMZ12001 Looking for a DC/DC power conversion module that carries an ATEX / IECEx certification for use in potentially explosive environments. It needs to handle 1-2 W, and have a 3.3V output (ideally with an input of 20V, 5V, or 3.3V). …
Other Parts Discussed in Thread: LMZ12001 , LMZ12001EXT TI E2E, I'm designing a step down regulator and came across the LMZ12001 module. It seems perfect for my application. It only requires a few external caps and resistors, it's pcb footprint is small…
Sorry for this late reply.
I go to see if I can transmit schematic and layout.
About decoupling :
- At the input of the LMZ12001, I have a 22uF/16V/X7R capacitor.
- At the output of the LMZ12001, I have the same in five copy 22uF/16V/X7R, actually the…
Other Parts Discussed in Thread: LMZ22005 , LMZ12001 , LMZ31506 Hi,
I am using a LMZ22005 Simple Switcher for generating 3.3V power supply, and I need some clarification about its minimum input working voltage. I found some contradiction in the datasheet…
Hi Marvin,
Lateral Thermal Resistance of FR4 (per square mm) =IF(velocity_lfpm>0;1/(0.23*mm*0.221/10);1/(0.23*mm*0.221/3.75))
1. Which cell can I find above equation in the top sheet of excel tool? I could not find it.
2. What is the reason customer…
from David ,
The thermal via size of 16 mil (0.4mm) is too large.
Our recommended thermal via (Finished Hole Size) is 0.2-0.3mm.
This is to avoid molten solder dripped into the vias pulling the package towards PCB surface and causing solder bridging. …
