Part Number: LM20145DESIGN-CALC Other Parts Discussed in Thread: LM20145 Hi,
I am looking to design a 3.3V to 1.8V 0.5A max SMPSU I have been looking at the LM20145. The design spreadsheet is suggesting a 0.45uH inductor at a switching frequency of 1MHz…
LM20145 has PVIN pin(power stage input supply) and AVIN pin(Bias input supply to the chip), the input currents to both pins really depend on the application conditions when the converter is switching.
If the customer wants to know the total input current…
