Part Number: UCC28910 Hi,
When output current is small, RPRL is calculated negative value as below and attached.
SLUC503B_UCC28910 Design Calculator.xlsx
How should I set RPRL in this case?
Or, is small current not allowed?

Part Number: UCC28910 Hi,
The equation is shown to calculate the ID_PK(max) on the datasheet as below.
Though VCCR is used on the equation(28), is this correct?
This is not VCCR but VCSTE(max), right?
Best Regards,

Hi,
VCCR is defined as CC regulation constant and it decides ID_PK as equation(28) with RIPK.
However, VCCR is nothing in figure 27(control law profile).
What is the role of VCCR?

Hi,
I have a question regarding 10.2.1.1 Design Requirements of the dahasheet.
fLINE is defined as below;
However, it is calculated as below though the minimum frequency is 47Hz.
Why is 57Hz used on this calculation?

Part Number: UCC28910 Hi,
It is written that "If the DRAIN current exceeds a second level of current (VCSTE_OCP2 / RIPK) it is not necessary to detect the fault for three consecutive switching cycles, the device will stop switching immediately." on the…
Part Number: UCC28910 Other Parts Discussed in Thread: UCC28C42 Hi,
My customer is considering using UCC28910, the load current is 40mA(max).
In this case, Lp(min) is too large as below;
They would like to reduce this inductance.
Should the dummy load…
