Hi Ohad,

1. No EVM is available. However, you may refer to https://www.ti.com/tool/TIDA-00122 reference design.

2. No SPICE model is available.

Thanks,

John

What is the leakage current in the CTRL pin at a temperature of -40C/ 125C?

2. How do I disable the ISET function or make the Slope Compensation very small and unnoticeable?

Hi Ohad,

1. This is not something we characterize or have data for.

2. You can set a very large resistor at the ISET pin, maybe close to 500k.

Thanks,

John

Hi John,

is there a way for to check regarding 1?

in addition, the UCC2850 is not good enough to test the functions of UCD8220, for example: CTRL,ISET,CLK,ILIM.

is there an expectation to have a PSpice or LTSpice model soon?

thank you!

Hi Shahar,

Regarding the "leakage current" at the CTRL pin, unfortunately, we don't have this information available. May I ask the motivation behind this question? Why is there a concern of a "leakage current"?

There is no active development for a PSPICE or LTSpice model.

Thanks,

John
