Part Number:TPS40210
I am looking for an upgraded PWM to the UCC2800 with an integrated soft-start and enable circuit and was able to find the TPS40210. The current UCC2800 is used in a fixed off time circuit application as is shown in an older application note. Would you know of any reason that the TPS40210 would not work in a fixed off time application? Also, there are two resistors internal to the TPS40210 that create the comparator equivalent voltage (2.65V on the UCC2800), is it possible to get values for those to calculate the timing if this component would support the fixed off time application?
Thanks!
