Part Number: UCC3808A-2 Dear Expert
End customer take another good D/C compare to current failure 4 D/C, we bought these D/C all has the same problem but the new D/C no any issue.
See below detail test report, hope u can check these 4 D/C 's problem.…
Part Number: UCC3808A-2 Hello,
As written in datasheet section 7.3.1, zeroduty cyclecan be externally forced by pulling COMP to GND.
So my question is when COMP pin is pulled to gnd, which input can impact the switching of the OUTA and OUTB.
Will the…
Part Number: UCC3808A-2 Hello everyone,
I would like to know the implications of the Current Sense Gain value (2.2 V/V) of the UCC3808A2 ( http://www.ti.com/lit/ds/symlink/ucc3808a-2.pdf ) in the control loop. Particullarty, let's consider the following…
Part Number: UCC3808A-2 Hello,
I am measuring the output voltage through a little sample of the it (voltage divider), and then a isolated Oamp is connected. I would like to know if what I am doing is right:
The UCC3808A-2 has particularly 2 pins to place…
Part Number: UCC3808A-2 Hello, I saw this part in a design where the FB pin (2) was getting 9 volts, datasheet says 6 volts max. VDD 14 volts. Was wondering if this could damage the chip.
The FB pin was being used as an enable/disable. Gets set to 9 volts…
Part Number: UCC3808A-1 Hello everyone, I am desiging with a Push pull topology a 500W DC-DC converter (Vin=24V +- 10%, Vout=200 V at 100 kHz). The current mode controller IC tha I am using is the UCC3808A-1.
The design (I followed Mclyman procedure) gave…
Hi Peter!
Thanks for your answer. I've another 3 questions:
1) Using ucc3808a in voltage mode like fig.28 can I keep also the current protection on CS pin from external circuitry? I read primary current of both switch on half bridge with a sense…
