Part Number: UCC2805-Q1 hello? My name is HL mando researcher Seongtaek Oh. Currently, we are using UCC2805-Q1 as a Flyback SMPS power device in our internal project. Here, the output of the SMPS (= used as gate driver power) requires more load. As a…
Part Number: UCC2805 Tool/software: Hi, I am using UCC2805QDRQ1 in a flyback design where the RC input pin is driven by an external oscillator and is not using the on-board reference. If a stable logic high is applied to RC, will the output of UCC2805…
Part Number: UCC2805 Other Parts Discussed in Thread: UCC2813-5 Hi,
Good Day.
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 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…

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 Dear Teams,
My customer is using UCC2805. Could you help them solve following doubts?
Vin: 8-32V
1. How to remove the auxiliary winding due to limited space of transformer.
2. Could customer us the Vout (10V) as the supply…
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…
