TPS62136: I want know the detail information about the VOS generate ramp waveform

Yan Wang2

Part Number: TPS62136
Other Parts Discussed in Thread: TLV62095

according to the internal diagram of TPS62136, there are a Error Amplifier and a Comparator in the TPS62136.

if the load current increase, then the voltage on Feedback point will be lower, then the Error Amplifier output will be greater, so how about the ramp generated by the "Direct Control and Compensation"? will it be lower or greater?

about the ramp waveform which was generated by the "Direct Control and Compensation", I see a ramp up waveform in the datasheet of TPS62136, but I see a ramp down waveform in the datasheet of TLV62095. So can you help figure out which one is right?

appreciate your feedback.

Yan,

We don't understand your question. Can you re-state it?

Hi John,

When the Vout is going to lower, what will happen on the Ramp out of "Direct Control and Compensation"?

and in the datasheet of TPS62136, the output of "Direct Control and Compensation" is ramp up. But in the datasheet of TLV62095, the output of "Direct Control and Compensation" is ramp down. so which one is right?
