My name is Meir and I am DFAE from Phoenix technologies in Israel.
One of my customers would like to simulate the ADP5023 by using the excell based ADIsimPower simulator.
As I understuood, the BUCKs of ADP5023 are based on ADP2138 core, is it?
Shall I evaluate the ADP2138 in order to get the results for ADP5023?
Here is a link:http://www.analog.com/designtools/en/simpower/?vinmin=11&vout=2.1&vinmax=1&iout=0.&tmax=55
We have dowloaded the tool fot it and after defining the parameters we can't get the ADP1038 option from the suggested list.
Here is the configuration for ADP5023:
Vout(BUCK1)=2.1V/0.5A - can't evaluate the ADP2138 - Why?
Vout(BUCK2)=1.2V/0.4A - can evaluate the ADP2138
Attached a file with the results from simulation tool:
Page1 depicts the Configuration, that ADP2138 option is not suggested
Page2 depicts the Configuration, that ADP2138 option is suggested
Please advise how can we simulate the the ADP5023 for above described configuration.
You are correct in that the bucks of the ADP5023 are fundamentally the same as the ADP2138. There are some parameters differences though, such as compensation, switch sizes etc. The reason that you cannot get the ADP2138 option for 2.1V output from the ADP21XX buck designer is that the part only has fixed output voltage 0.8, 1, 1.2, 1.5, 1.8, 2.5, 2.8 and 3.3V. The ADP5023 is available for fixed output 3.3 V, 3.0 V, 2.8 V, 2.5 V, 2.3V, 2.0 V, 1.8 V, 1.6 V, 1.5 V, 1.4 V, 1.3 V, 1.2 V, 1.1 V, 1.0 V, 0.9 V or adjustable. Contact a local sales or distribution representative for fixed output voltage options.
We are working on the buck design tool for the uPMUs: ADP5023/24/33/34/37/40/41&ADP5133/34/35 and it will be available for downloading soon. For you reference, attached is the result from the preliminary tool for your design.
