Perhaps you can look at the LMZM33606 which integrates the LM73605 converter. Figure 67 shows a typical soft-start sequence. The delay time looks roughly half a division which comes out to around 1ms. There will be some additional delay glitch time of…
Hi,
Unfortunately I didn't get a response from the designer on this expected efficiency drop. I plan on taking the LMZM33606EVM and configure it for positive output to measure the efficiency at 1MHz and 2MHz. That way I can at least provide you with…
Hi Yusuke-san,
My hope is to spend some time today in the lab to bench test the synchronization on the LMZM33606EVM and provide you information today or by latest tomorrow similar to the data I got for LMZM33603. Sorry for the delayed response and I…
Hi Liu,
The reference of the LMZM33606 is set to regulate around 1V as you've seen in the datasheet.
The 1.5V feedback voltage you see is for when you want to check the Iq current of the device. To get the part to a non-switching state, the feedback…
Hi Yusuke-san,
The LMZM33603 power module only operates in "Active Mode" which is basically FPWM( Section 7.4.1 ). This is in continuous conduction mode with fixed switching frequency. There is no PFM option for the LMZM33603.
If you are interested…
Hi d.
d_zero said: So you would suggest to use either 2.2u with 16V or 1u with 50V.
Yes. 2.2u with 16V maybe better for higher effective capacitance.
d_zero said: Did you check the schematic and excel calculation, do you see any potential problem…
Hello Yumiko,
There are various ways to filter input and output noise. I've attached a few Application Reports in which I believe can be helpful information. Also, please take a look at the previous post ( link ) which is similar to your question. …
Unfortunately, I do not have an exact recommendation. Selecting the correct Ferrite Bead filter varies through applications. But, below I have provided some technical documentations in which I believe can be very helpful if you are planning on implementing…
