TPS610333: Frequency synchronization function concern

Irene Qin
Intellectual 1770 points
Part Number: TPS610333
Other Parts Discussed in Thread: TPS63070, TPS61030, TPS61033, TPS61178

Hi team

I found TPS610333 show "Frequency synchronization" in the public page as below: but didn't find this function in datasheet, so whether TPS610333 has Frequency synchronization function?

And customer requirement as below :

Input voltage range :2.7~4.2V, output voltage 5V, output current 0.4A, Frequency synchronization function needed, internal switch or internal inductor both works. Current limit 2A~3A. small size

I didn't found a device that could meet the above requirement, so I proposal TPS63070,

May I ask do you have other better proposal for the above requirement?

Best regards

Irene qin

    Hi Irene,

    Sorry that there should be some mistakes here, TPS61033 doesn't have frequency synchronization. I think you can promote TPS61030 or TPS61178, they have SYNC pin, that can be used as frequency synchronization.

    By the way, do you know why customer needs frequency synchronization? What is the application? Our boost device seldom has this feature, so I want to know why customer need this. Thanks.

    Regards,
