UC1525A: Dead time configuration

George Zhao

Part Number: UC1525A

Hi team,

I wonder how to choose a specific Rd for a specific dead time? I only see in Figure.2 the relation between Rd and Charging time, how is the charging time related to the dead time?

Thank you very much!

Hey George,

Figure 2 is actually the relation between Rd and Discharge Time. There is an error in the graph, but not the title.

Thanks,

Daniel

Hi Daniel,
Thanks for your reply.
But I'm still not very sure about the relation between discharge time and dead time. For example if I want a 100kHz frequency and 100ns dead time, how can I choose Rd? I'm afraid the datasheet doesn't specify.
Thanks!

George

Hey George,

The discharge time is the dead time of the circuit.

Thanks,

Daniel
