TPS566235: Availability

Hi, this is a high efficiency and low cost part. provide your application condition, such as Vin, Iout...., the more information, the better. Let me check whether it is proper.

Do you need more support here? if not, this thread will be closed..

I will use a different regulator

Hi Howard,

    Any specific reason you are moving away from this regulator? Any specific features that you are looking at.

You can use the WEBENCH tool to help with selecting the right switching regulator.

Hi Howard,

    Can you please let us know your power requirements?

For Negative voltages - I will be using a different regulator.

For Positive voltages - I am designing this in.

Since there is no data sheet info on efficiency, and simulator does not work in that mode I must go that way.

The negative voltage requirements are:

-12.2V At 200 mA

-3.5V at 1 A.

Battery input is 10.5V nominal.

Hi Howard,

   I was able to find some devices for your requirements. 

Here is a WEBENCH shared design for these requirements.

For -12.2V @200mV: LMZM23601 power module

For -3.5V at 1A: TPS63710 inverting buck converter
