Modules MPM3506A MPM3606A MPM3606

DC-DC Power Converters
1

My task is to power the microcontroller from USB-C PD. The voltage is always floating, from 5 to 20 volts.
For obvious reasons I can’t use LDO. And I make a choice in favor of the following modules:
MPM3506A
MPM3606A
MPM3606
They have a maximum current of 0.6A.

My microcontroller and peripherals consume about 100mA.

Question:
Will these modules suit me if the input voltage changes in the range of 5-20V?

If the answer is yes, then which of these modules is best for me?

Please give a detailed answer. Thank you!

Hi,

I will recommend MPM3506A. Because MPM3506A is more efficient for load = 0.1A. And the input range for MPM3506A is safer for your application.

MPM3606A is based on MPM3606, change AAM pin to PG pin.

Tell me, is there perhaps a better solution to my problem? I mean a ready-made module.

I came across this module MPM3612-33, tell me, based on my task, which one to choose?
MPM3506A, MPM3612-33 or something else?
Thank you!

Hi,

For your application, Vin = 5V to 20V, Load = 100mA. If you only need 3.3V output I think MPM3612-33 is better, and I think it is the best choice. You should make sure you will not exceed the input limit 22V. If you have other requirements please let me know, I will give you more suggestions.

What can you say about the following modules MPM3509 and MPM3509B?
How do they cope with a small load? Or are you still leaning towards the MPM3612-33?

P.S.
My task is to power the microcontroller (3.3V) on the board from USB-C PD. The voltage range always changes depending on Power Delivery support.

Hi,

MPM3612-33 is much better than MPM3509/MPM3509B for your application.
