One of our design we have considered "LM60430" for 5V to 3.3V conversion with 2A Max output current.
I have bit confusion to selecting an switching Inductor .
As per our requirement the output current is min 1A, Tpy 1.6A and Max is 2A.
When I calculating the inductor selection as per datasheet is showing 3 different value when I consider different output current but it is as per the calculation.
I would like know how to choose right inductor value when our output load current is wide range.
Please provide details information about this.
Parameter | Min | Typ | Max | ||
Input Voltage | Vin | 4.75 | 5 | 5.25 | V |
Output Voltage | Vout | 3.234 | 3.3 | 3.366 | V |
Fsw | 1000000 | Hz | |||
Design Output current | I_out | 1 | 1.6 | 2 | A |
Ripple current Ratio | K Ind | 0.2 | 0.3 | 0.4 | |
Switching inductor | L_out | 1.50989E-06 | 2.3375E-06 | 5.16078E-06 | H |
