I have a question about ADP2118.I'm useing ADP2118 in the following condiiton; Vin-5V, Vout-3.3V(Duty: about 0.7).But how should I caluculate Minimum vallue of INDUCTOR?I can't find any caluculating fomula on the datasheet.
Since ADP2118 has current mode output, I assume that it is possible to connect two or more of these converters in parallel to increase the current output. I want current output of 6A whereas ADP2118 can support 3A continuous current.
But in the…
The transient response of a switching regulator depends on several factors; primarily the regulator’s architecture (voltage mode or current mode), the switching frequency, the value of output capacitance, and the inductor value.
The value of output…
ADP2118's PGOOD terminal is open drain output.
Is it ok floating when PGOOD doesn't use?
Datasheet said PGOOD is an active high, open-drain output and requires a resistor to pull it up to a voltage.
Any problem if that terminal was open…
load transient depends on the ammount of capacitance added to the output.
You may want to consider using the ADP2120 design tool to identify how much capacitance you will need for a specific transient requirement.

Some of the legacy products (ADP182x family) use the voltage mode control. Few variants of Current mode control architecture are predominantly used in all the recently released controllers and regulators from ADI. These variants are:
Peak current mode…
As far as using the TRK input goes in the manner you described, it will work. However, there are other factors to consider specific for the application you just described.
1) ADP2118 has a fixed internal compensation. This means that the external component…
