Customer would like to ask you a few questions that arise in the framework of a new design that currently is being developed.
The new PSU design is indented for automotive…
Part Number: UCC2805-Q1 Other Parts Discussed in Thread: UCC2805 , UCC2801 , UCC2803 , UCC2802 , UCC2804
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 Dear team,
Customer has several question about ucc2805:
1. As the start-up current is very small, R491 should be tens of K Ohm, but I found that only Vin 12V, R491=2k that the system could power on normally. But if R491 is small…
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.
Part Number: UCC2805 Dear Teams,
My customer is using UCC2805. Could you help them solve following doubts?
1. How to remove the auxiliary winding due to limited space of transformer.
2. Could customer us the Vout (10V) as the supply voltage…
Part Number: UCC2805 Hi,
I have to simulate UCC2805 in Altium Designer. I begine with unencripted model that I found at TI web page.
Due to syntax issues I modified an simmulation do not retur any error anymore, component is not working.
Below I am sending…
The same datasheet
If you look at Section 8.5, oscillator, and UCC2805 note (2) you will see:
"(2) Oscillator frequency for the UCCx800, UCC2802, and UCC2803 is the output frequency. …
