Other Parts Discussed in Thread: SN65176B
Hello iam designing my first Boost converter in Webench,iam taking 3.3V @ 2.1Mhz and boosting it to a 5V output.iam just running a start up simulation and the waveform seems to get a ripple of around 10mV.Now i know the simulation is just that a simulation but if iam getting what seems high to me ripple voltage in a simulation,then iam assuming in the real world it will be higher.
The only IC drawing power from this Booster is a SN65176B which should only be around 60ma max.So first should i be worried about this?Two is there anyway to get rid of the ripple without adding a LDO to the output side?Thanks any input is appreciated.There should be a image attached showing my schematic and waveform.The Source and Input capacitor values are a little obscured so the values are posted below.
