FAQ
Improper layout can cause some IC's not to operate correctly, as an example let’s use the ADP2108.
The part has a 3Mhz fixed operating frequency. You will want to place the input cap, output cap and inductor as close as physically possible to…
Hi all,
First of all: hobbyist here, first time using one of these switchers. I've not followed the recommended layout and possibly made some other mistakes.
However...
I am using an ADP2108AUJZ-3.3-R7 in a design that will be powered of a Li-ion…
Hi.
I have applied the described solution, but the voltage is somewhat higher than the nominal and the load is only a resistance of 330 ohms. What could be the problem? (Vout will be 3.0 and it is 3.26 to 3.4 aprox.)
Here is an image of the output voltage…
Hi,
I have the same situation as several other posters with an ADP2108-3.0 whose output sits at about 1V. With the output at 1V, my circuit is drawing about 45 mA.
I have added a 4.7 uF X5R 0603 input capacitor across Vin and ground, still doesn't work…
