Part Number:TPS61088
hello support team
The efficiency of TPS6188 will be same for both of PFM and PWM mode on normal load condition according to Figure 1 and 2 in datasheet.
But the efficiency by Webench is different each mode like below.
PFM mode : 95.5%
PWM mode : 90.6%
Could you please check the Webench models and let me know the reason why they are different.
Best Regards,
Hirokazu Takahashi
