Other Parts Discussed in Thread: LM20133, TPS54350
Hi Team,
Our customer needs a synchronous DC/DC converter with frequency synchronization from external source. The LM20133, LM20333 and TPS54350 seem fit for his application, however, there are no information in the datasheets regarding the settling time of the devices (probably due to the internal PLL), when the external sync frequency is changed (NOT at startup).
According to our customer, in his application, the external frequency could be changed very often, while the component is regulating power. He needs to know how the component will behave when the SYNC frequency is being changed.
Is there any data on how long it takes for the component to settle when the SYNC frequency is changed? Or is this something that he have to determine by bench-testing? It seems like it is not a typical scenario for a synchronous DC/DC converter.
Regards,
Danilo
