Other Parts Discussed in Thread: TPS63020-Q1

Hello,

In the datasheet Figure 11~17 of TPS63020-Q1, there are the Load Transient Response, Line Transient Response and Startup After Enable data on the condition of PS/SYNC = High(Power Save Disabled).

Could you please share the similar data on the condition of Power Save Enabled?

Hi Ryuiji,

I send you the curves by message. But as a general comment the device I measured is already switching in PWM mode for a load of 500mA and above. So basically the curves remain similar.

Could you share details on the application?

What are the operating conditions? What is the customer concerned about?

Hello Sabrina,

Thank you for your support.
I understood that the DRL is worse from PFM to PWM.
I will check their dynamic load transient condition.

Hello Sabrina,

In the customer there are the following use case

0mA <--> 100mA , 100ms cycle
0mA <--> 300mA , 1ms cycle

I think that they should use the device on the fixed PWM mode.
