UC1875-SP: 180deg Phase

Part Number: UC1875-SP
Other Parts Discussed in Thread: UC1825B-SP

Hi Team,

My customer is looking at using both the UC1875-SP and UC1825B-SP in a new application. We would like to understand if either of the two products can be configured such that Vgs1,2 and Vgs3,4 can operate 180deg out of phase with each other and above 50% duty cycle? It seems like it can but would like your confirmation.

Thanks,
Mitchell

Hey Michell,

What topology are they planning on using?

The UC1825B-SP definitely won't be above 50 % duty cycle and the UC1875-SP is a very specific control scheme that generally doesn't work with other converters.

Are they typing to do a synchronous buck?

That's usually what they are looking for when asking these types of questions.

Thanks,

Daniel
