TPS61376: TPS61376 output capacitance limits

hwswdesign
Intellectual 310 points
Part Number: TPS61376

Tool/software:

The datasheet for the TPS61376 gives the recommended max output capacitance at 2000uF. Due to the pulsing nature of my load, I have found that I need 4700uF or more.
Is there a reason I can't use 4700uF or more output capacitance on the TPS61376?

    Hello,

    Too much capacitance affects loop stability. You can still try adjusting compensation parameters to achieve enough loop stability. But we never tested and do not guarantee the loop stability.
