Regarding [Current Limit and Short Circuit] of LMR43620-Q1 The formula for calculating the limit current value for overcurrent protection is not in the data…
Part Number: LMR43620-Q1 Tool/software: Hi Team,
Can you tell me the formula I can use to calculate the following for the LMR43620-Q1?
・Total voltage sag ・Overshot voltage ・Output voltage ripple
Part Number: LMR43620-Q1 Tool/software: Is it possible to use equations (5), (12), (13), and (14) from the application report "Basic Calculation of the Power Stage of a Buck Converter" to calculate the values of the inductor, input capacitor, and output…
Part Number: LMR43620-Q1 Tool/software: Hi team,
I'm BCCing this thread to my customer. Could you provide I_BIAS value? They cannot use below formula.
If they connect EN to VIN, we should append I_LKG-EN terms to the above formula, right?
Out of…
Part Number: LMR43620-Q1 Tool/software: Hi team,
My customer want to check their inductance selection. Here is their calculation.
And they want to use inductor which have 20% variation. So the worst case is;
2.75uH > 3.3uHx0.8 = 2.64uH
2.75uH < 4…
Part Number: LMR43620-Q1 Tool/software: Hi team,
Would I know how we can "calculate" the output voltage with using external components values? Some other e2e thread mentions it can be done by Spice simulation but we like to understand theoretically.…
Part Number: LMR43620-Q1 Other Parts Discussed in Thread: LMR43620 Please submit the materials of the Qualification summary.(LMR43620MC5RPERQ1) I could not search on your website.
Part Number: LMR43620-Q1 Other Parts Discussed in Thread: TPSM33615 , LMZM23601 My customer is using MPM3509GQVE. What is our device to compete with MPS?
Note: The CrossRef tool does not know MPM3509GQVE.
Thanks

Part Number: LMR43620-Q1 Hi team,
I would like to minimize current drawn from the battery and would like to increase feedback divider resistor value as high as possible.
The input bias of FB pin seems very low (10nA), I want to use 330kohm (R FB total…
