Hi Expert,
UCC2805-Q1 was used on customer side. When they configure frequency based on the formula in datasheet. The resistor is 15k, and the…
Part Number: UCC2805-Q1 Other Parts Discussed in Thread: UCC2805 I have a question regarding the UCC2805 Over Current function. Since the COMP pin is clamped at 1V when the secondary output is in an over-current state, the PWM is always reset when CS…
Part Number: UCC2805-Q1 Hi Expert,
The engineer is using the UCC2805-Q1.
Pls help to clarify the question about frequency behavior.
They are setting 100kHz from (10k +1000pF) on RC pin.
The results is 100khz on output pin and 200khz on RC pin…

This is related question to above E2E question.(same customer,same application)
Customer consider to add OVP circuit.
When OVP is detected,they make low COMP pin.We have question in…
Part Number: UCC2805-Q1 The customer uses UCC2805-Q1 and transformer to constitute flyback isolated power supply. Could you please answers for the following question related to UCC2805-Q1.
Q1. If the voltage input to the FB pin shorted to 0V, will the…
Other Parts Discussed in Thread: UCC2805-Q1 Hi team,
Could you please answers for the following question related to UCC2805-Q1 max rating?
1. Absolute max rating voltage of VCCis 12V in datasheet. And 13.5V is clampped in the block diagram. So could…
Hi Steven, Thank you for your reply. Here's the Rev D slus270d.pdf Kindly see below the snippets.. Furthermore, I've checked the SLUS270F, it seems that the "line regulation" for the UCC380x is not copied on SLUS270G. Can you please help confirm? Thank…
