TPS561201: EN, UVLO and Current limit specification when using this part as inverted DCDC converter

user4292685

Part Number: TPS561201

When I use TPS561201 as inverted DCDC converter, EN, UVLO and Current limit specification might be different from one in normal buck converter usage.

Could you tell me how to change these specifications?

I pna to use this DCDC in an inverting DCDC, so the spec in datasheet is not suitable for this case.

As mention above, the spec in datasheet is not suitable for this case.

hi,
You mentioned that you want to use TPS561201 as inverted DCDC converter. the structure/schematic should be complex and it is not the typical application for TPS561201. Please send your schematic to Anthorny to discuss. email address: anthony-lang@ti.com
or seek a boost converter for your application.
