Dear Sir or Madam
We are going to use TPS43061 controller. We found, that some results from WEBENCH design do not match with TPS4306x_BOOST_CALCTOOL_REVB.xls tools (and Datasheet calculation). For example, WEBENCH gives cross-over frequency 15kHz, Phase Margin 50°, Gain Margin 10dB. We used component's value from WEBENCH design in TPS4306x_BOOST_CALCTOOL_REVB.xls and got cross-over frequency 8.7kHz, Phase Margin 53° and Gain Margin minus 9dB (excitation). It is not small mismatch but completely different result. As our new product is going to be used in a number of different input and output conditions, we would like to simulate (transient and frequency respond) all these conditions and also worst case condition (component's tolerance). As this controller does not have unencrypted model, could you please, provide more information about this controller:
1. Parameters of slope compensation signal
2. Parameters of Error Amplifier output: Does it sink current or source current or both and what is the its output current limits.
We would really appreciate your help
Regards
Lev
