For the PF8200, is it important to have the voltage on VIN match the voltage on the Switch and LDO inputs? (SW1IN-SW7IN and LDO12IN-LDO4IN). Or can VIN be run at 3.3V while the Switch and LDO inputs are at 5V?
I just created a thread about exactly this topic few days ago: Different inpult voltages lead to destruction???
So, despite the datasheet saying nothing about it, this is not allowed.
Oh wow, thank you for linking that thread. I'm really glad I asked this question. Thanks for the info!
Don't suggest your do that! Using VIN different from SW and LDO input.
Hi G.W. Sun,
Thanks for the response. Would it be safe for me to have VIN at 5V, and SW and LDO inputs unpowered (at 0V)? Or will that also break the PF8200?
