Other Parts Discussed in Thread: TPS2546
Hey champs, so the TPS2549 datasheet, while maybe not specifically calling out a capacitance of 150uF; certainly references it a lot as far as the specs go... so was wondering the source of this. Is there a reason we need 150uF on the output? The reason we're asking is that the design has a 3.5A DCDC feeding this; and obviously making this capacitor that big will require a larger current when it turns on. In the past we had used the TPS2546 at a lower current (2.1A max) and had used 22uF cap on the output of that device, and never had any issue. So wondering if we need the 150uF there for this newer part, and what's driving this need.
