TPS63070: Maximum output capacitance, SOA

Jason Petras

Part Number: TPS63070

Hi TI,

I would like to put 3000uF to 5000uF output capacitance on my TPS63070. Unfortunately, the datasheet does not discuss limits, or gives SOA information. Can you please help me understand the limits and considerations?

Caps are poly tants 591D158X06R3R2T20H.

Thanks!

Dear Sir,

TPS63070 supports big cap startup. But make sure the maximum current of the inductor is higher than the maximum current limit of the silicon, which is around 4A.
