Part Number: LMR43620-Q1 Hi
I'm planning on to use the LMR43620MSC3RPERQ1 and wanted to confirm in order to make the converter to work in FPWM mode always (VMode > VMode_H), is it okay to tie the MODE/SYNC pin directly to the VCC pin ?
The datasheet…

Part Number: LMR43620-Q1 Other Parts Discussed in Thread: TPS57140-Q1 , , LMR43620 hi Friend,
In the previous specifications of your company, you can see the calculation formula of VOUT and partial voltage resistance, but not in LMR43620-Q1. May I ask…
Part Number: LMR43620-Q1 Hi team,
I would like to know the output behavior of LMR43620-Q1 for VEN-VOUT < VIN < VINMIN.
Since there is no description about input UVLO except precision EN and boot UVLO, I believe the device will
start switching in…
Part Number: LMR43620-Q1 Hi team,
Customers tested using LMR43620MSC5RPERQ1 and found: When UBATT=6.8V, the load can only reach 1A. UBATT=12V, the load can reach 2A.
Please tell me, when the input voltage is low, why is the load capacity not strong? Does…
Part Number: LMR43620-Q1 To check the switching frequency of the LMR43620Q1, I used a probe between C65 and L9 in the picture below.
There is something strange about the switching frequency. There is some distortion on the rising edge of the square waveform…
Part Number: LMR43620-Q1 I want to check the fault when the LMR436x0-Q1 output terminal is abnormally operated.
and apply a voltage to the output voltage terminal that is larger or smaller than the normal voltage.
However, the PG signal did not low I would…
Part Number: LMR43620-Q1 Hi team,
We want to promote our LMR43620-Q1 to replace RTQ2130 and MPQ4432.
Could you please help check if we have advantages compared with RTQ2130 and MPQ4432?
Thanks,
Brian
Part Number: LMR43620-Q1 Hi team
1. Could you tell the role of the filter below?
2. Is the input filter mandatory for the customer's system to pass CISPR25?
3. When the fsw is 2.2MHz with the PFM mode and external sync is not required, is it…
