Part Number: UCC28780 We have several dc-dc modules designed with UCC28780 controller.
We obtain all design values from the spreadsheet SLUC664b.
Consider a design with 380V DC input with very little input ripple, output 5v/4 amp, we use NV6117 primary…
Dear Moritz,
we have seen that our Iout is very low, near to 70mA supplied . Our Boost enters in CCM only for Vin< 3,8V.
We have to change inductor with 250-350uH one.
Moritz said: Please try 5k, 200n, 1n.
Considering your suggested compensation…
Part Number: UCC28950 Hi,
I have designed the power supply using UCC28950 according to the spreadsheet SLUC222D and I am now trying the simulation for it but I am not able to achieve the desired result.
Q1. The spreadsheet is showing shim inductance…
Part Number: BQ25730 Other Parts Discussed in Thread: BQ25731 Hello,
We have been using a BQ25731 charge controller for a while and have been successful with charging with this device. We have switched to the BQ25730 device, based our product requirements…

Part Number: BQ77915
Hello team,
I am designing a prototype BMS which can be used for 10S/13S/15S li-ion cell combinations with current limit options of 1.2A/10A/25A/120A. BQ7791500 is the selected part number.
Switch S1 can be used to select…
Martin,
As I mentioned previously, we do not have such information. Our Modules are for commercial use therefore those tests are not performed.
I would recommend going to ti.com, click on top left corner "Applications" and select "Aerospace & defense…
hello Ben
Power designer uses FET frequency which is half of Lout frequency. so for 100kHz In power designer we have to keep 200kHZ in sluc222c is it not? which recommends same values i listed in previous comments and its not consistent.
Even in file…
