TPSM63602: Negative configuration

Sariel Hodisan

Part Number: TPSM63602

Tool/software:

Hello,

I am planning to use the TPSM63602 in IBB mode to produce -5V up to -15V/ 2A (will change pending design with different FB resistors) with an input voltage range of 12-24V.
There is little information in the datasheet regarding this configuration and I might easily make a mistake.

I would appreciate it if you could provide me feedback regarding this design.

Thanks.

Hi Sariel,

Thank you for your question. As you are utilizing a module for this IBB, I can recommend this application note that takes a similar module through the design process for a successful IBB application. One major thing to note is that the app note is for a 4 A device, and the TPSM63602 is a 2 A device. However as long as this is accounted for in the section 1.2 equations and any other equations with current, this application note should help guide you through your application.

Of course, if you have any additional questions past this application note, please don't hesitate to ask.

Thank you,

Joshua Austria
