Using STM32 to synchronize a multiple output power supply

Hi all, 

I want to start using STM32 MCU in order to synchronize a multiple output power supply with a single frequency.

So for I have used an anlog PLL (74HC4046) for this purpose:

1. The relevant range is 200-500 Khz.

2. If the external freq. is out of range or doesn't exist the internal 400Khz clock will distribute to all module. 

First of all, is it possible? 

and if so, are there any examples?

I am using STM32L053 Discovery.

Thanks.

Dear

g.omri

,

Welcome to STM32 community

The STM32CubeL0 firmware package comes with a rich set of examples as described in

http://www.st.com/content/ccc/resource/technical/document/application_note/c4/d9/35/24/7f/10/49/fc/DM002097pdf/files/DM002097pdf/jcr:content/translations/en.DM002097pdf

and there is several PWR examples at this path: STM32Cube_FW_L0_V1.8.0\Projects\STM32L053C8-Discovery\Examples\PWR

You can refer to the manual

http://www.st.com/content/ccc/resource/technical/document/reference_manual/2f/b9/c6/34/28/29/42/d2/DM000957pdf/files/DM000957pdf/jcr:content/translations/en.DM000957pdf

,is your reference for more clarification.
