Other Parts Discussed in Thread: TINA-TI, TPS82130,
Tool/software: TINA-TI or Spice Models
I wanted to evaluate start-up behaviour with Vin = Vout, to see when the TPS62130 would stop switching. When I tried the simulation in Webench with TPS82130 (which has TPS62130 'core'), it behaved as expected, going to 100% mode at about 400 us, really, at about the time that Vout reached the correct 'trip point' for 100% operation, but the Tina-TI simulation did not seem to switch to 100% mode... Vin at 5.1 V, Vout 5 V
TPS62130 here, in Tina-TI, below, sim results from 82130 from Webench
Webench schematic... feedback resistors same for both cases
