TPS62065-Q1: Efficiency Graph of Auto Mode vs Forced PWM mode at Vout = 1.2V

Part Number: TPS62065-Q1

Hello,

I want to compare the efficiency between Auto mode and Forced PWM mode when Vout is 1.2V. 

Are there any graph like a Figure 14 which is for Vout = 1.8V?

Regards,

Furuya

  • For efficiency information at different test conditions I recommend to use Webench. This also allows you to change parameters of the passive components used in the circuit and see the effect.
    In your case I would expect that the efficiency is 3-4% lower than the 1.8V data because of the lower output voltage and the corresponding lower duty cycle.
  • Juergen,

    I already tried to use Webench, but it showed only Auto mode efficiency.
    Can Webench support FPWM mode for TPS62065-Q1?
    If there are any way to show the efficiency of FPWM mode of TPS62065-Q1 on Webench, please let me know.

    Regards,

  • Unfortunately the WEBENCH model does not support switching to FPWM yet. I just requested to add this feature.
    To support your analysis I just sent you efficiency data by email.
