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 capacitor…
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 reaches…
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.
Pls advice…
