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…
Part Number: LMR43620-Q1 Hi Team,
My customer is using LMR43620Q1 in their design. From my point of view, if we use FPWM which means that the switching frequency will be fixed in my operation.
But I found that if our load current was low(400-600mA…
Part Number: LMR43620-Q1 Hi team,
LMR43620-Q1 doesn't have a pin/function to turn on/off the spread spectrum anytime we want, right?
In the datasheet, it seems that this device has a option to not have the spread spectrum.
But in the device comparison…
Part Number: LMR43620-Q1 Hi team,
What is the RT (frequency setting resistor) value for 2.2MHz Fsw using RT variant?
Table 8-2 of the datasheet suggests RT input can be tied to GND. But from Figure 8-7, several k-ohm resister is required to set Fsw 2…
Part Number: LMR43620-Q1 Hello Team,
Please clarify the inductor calculation to consider in design,
As per the datasheet inductor value is 50uH. But WEBENCH simulation window shows 2uH.
L=[(16V-8.8V)/(2.2MHz*0.3*0.12A)]*[8.8V/16V)=50uH
Vin=16V max
Vout…

Part Number: LMR43620-Q1 I am using LMR43620MSC3RPERQ1. On the page 38 of datasheet, it states "If the application is operating close to the minimum input voltage, this dip can cause the regulator to momentarily shut down and reset. The best way to…
Part Number: LMR43620-Q1 Hi,
The LMR43620-Q1 datasheet lists a range of allowed parallel FB resistance of 5k-10k (I assume to ensure loop stability). However, Webench seems to assign larger values - similar to what you would expect based on the datasheet…
Part Number: LMR43620-Q1 Hi Team,
What is the voltage accuracy for the 5V fixed version of the LMR43620-Q1? Datasheet is only showing the 3.3V fixed tolerances:
Thank you,
