TPS62366B: Vout accuracy at PFM mode

Takashi Yamaguchi

Part Number: TPS62366B
Other Parts Discussed in Thread: TPS62864

Hi team,

My customer is considering to use the TPS62366BYZH. They would like to know the Vout accuracy at PFM mode.

The Vout accuracy in PWM mode is characterized as +/-0.5% on the E.C table with the condition of no load, Forced PWM, VOUT = [0.77V,1.3V] Tj=85degC. Could you let me know the Vout accuracy in the PFM mode with the same condition?

I also have other question below.

Regarding the Fig.38(Switching frequency vs. Output current) in the d/s, the unit on the horizontal axis of this figure is "A", not mA, right?

Regards,

Yamaguchi

Hello Takashi-san,

Did you have a look at the Figure 11 to 14 in the datasheet ?

I could provide more details on those if necessary.

Regarding the Fig 38, you are correct. This is a typo. I will ask, so this can be corrected.

Did you show the newer TPS62864 to the customer ? I would recommend you use this part for customer's new design.

Thanks a lot!

Regards,
Dorian

Hello Dorian-san,

Thanks for the information. I will let customer know the Fig 11 to 14. If you also have more detail about the accuracy in PFM, could you provide me it?

Thanks for the proposal of TPS62864. I will propose it to the customer.

Regards,

Yamaguchi
