Part Number: LMR33630ADDAEVM I made the circuit from WeBench for a -12V switcher using the 33630 part and when I apply power, it just crowbars the input supply. As I ramp up the input starting at 0, there is no current, then at about 3-4V, it shorts and…
Part Number: LMR33630ADDAEVM I'm working on a buck regulator to bring 16-30VDC down to 14V. It seems to be working nicely but I'm seeing jitter on the PWM.
It looks a bit like frequency dithering to mitigate EMI issues , but I see nothing mentioned…
Part Number: LMR33630ADDAEVM Other Parts Discussed in Thread: LMR33630CDDAEVM Hello guys,
One of my customers is considering using LMR33630BDDA(3A/1400kHz) and LMR33640DDDA(4A/1000kHz) for their new products.
They want to evaluate these devices using…
Part Number: LMR33630ADDAEVM Hi Team,
I have a question about LM33630EVM.
Why Vin=24V, Vout=5V/3A. SW spikes are small or even none but vin=8V Vout=5V/3A. SW spikes are bigger.
Could you tell me the reason?

Part Number: LMR33630ADDAEVM Hello team,
I'm testing the EVM mentioned above but I didn't find on the Datasheet the copper layer thickness. Could you please provide this info? Or at least indicate where to find it?
Also, how can I run a thermal…
Part Number: LMR33630ADDAEVM Hello,
Copied circuit of LMR33630A from TI application notes (L is 8.2uH) except we used one 330uF Aluminum Capacitor, one 22uF ceramic one at the output. Feedback Resistors are 100k/24.9k.
Designed 24V in/5v out. Very…
Part Number: LMR33630
I have simulated the LMR33630ADD using the same components as defined in the datasheet and on the evaluation board (LMR33630ADDAEVM). The only modification made was to adjust R2/R3 to achieve an output voltage of 18V in the step…
Part Number: LMR33630ADDAEVM Other Parts Discussed in Thread: LMR33630 Hello everyone. I would like to do a transient analysis of a DC/DC converter using PSpice For TI. However, the DC/DC converter IC (LMR33630) is not working properly. What should I…
Hello,
You can simulate an input line transient using Webench, I've shared a design with you below:

The best way to test would be to test this on an EVM and see if the output…
