TPS61093 – About Load transient response

Guru 21045 points
Other Parts Discussed in Thread: TPS61093

Hi,

 

My customer uses TPS61093 on the following condition.

However, The Load transient response turns worse only at the time of "Vsw = 3.8V (Power stage input)".

Does the Load transient response depend on the power stage input?

 

We would like to ask the cause of this problem.

Could you please give us your advice?

 

-------------------

[Conditions]

Vin = 3.3V

Vsw = 3.0V to 4.6V (1cell battery)

Vout=12.4V

Iout = 3mA to 20mA (Load transient)

 

* please refer to the attached file.

-------------------

 

I would like to send my customer's waveform to you.

Could you please tell us your e-mail address?

 

Regards,

Kanemaru
