BQ25720: input/output cap for 130W design

Fred Cheng

Part Number: BQ25720

Hi team,

datasheet specify 9x10uF MLCC+2x22uF POCSCAP for output cap,

customer now use 9x10uF MLCC+ 1x15uF POSCAP,

is this ok?

is the additional 22uFx2 POSCAP necessary ?

Hi Fred,

Please follow our datasheet recommendations. It should be Okay since they may have more output capacitance spreading out on the whole board.
