Part Number:UC2525A
Hi Bros,
My customer is using UC2525A to design 5 channel half bridge power which using sync function. For the first UC2525A, it is in master mode. Change the R27, the frequency can change from 800Hz to 1.5KHz.
For the other UC2525As, they are in slave mode.
During testing, we found the slave frequency cannot always the same as the master especially when the master frequency is higher than 1.35KHz. I cannot find anything relationship between the sync frequency and RT,CT frequency. Do we have anything equation to set the slave UC2525A's RT, CT, RD in OSC mode? Thanks.
