Part Number: UCC21520 Tool/software: Hi，
The specification sheet of UCC21520 provides a solution for Negative Bias with Zener Diode on Iso Bias Power Supply Output. But if my power supply has three outputs, namely VDD, GND and VEE. VDD2=18V，GND，VEE2…
Part Number: UCC21520 Hi,
I have UCC21550BQDWRQ1 circuit, which is attached. The PWM controller is UCC28086D at 33kHz. The input works fine. Concerning the output, only the OUT B is switching ON/OFF but the OUTA goes high and reads 10V, i.e., stays ON…
Part Number: UCC21520 Tool/software: Hi,
I want to ask question regarding using relay (G5Q-1A4-DC12) at the switch node of half bridge circuit to connect and disconnect individual transformers contacted in parallel to the circuit. See the attached image…
Part Number: UCC21520 Tool/software: I am using the UCC21520 to drive an IGBT in a half-bridge configuration (SKM100GB12T4 from Semikron). My intention is to apply +15V to turn it on and -12V to turn it off. Based on the datasheet, I believe Figure 10…
Part Number: UCC21520 Other Parts Discussed in Thread: UCC21330 , UCC21551 , SN6501 Hi TI.
I am looking for a driver solution that is specific to a type of cycloconverter. I have already successfully utilized UCC21520 for the development of a Dual active…
Part Number: UCC21550 Other Parts Discussed in Thread: UCC21520 Hi team,
Could you provide a UCC21520 and UCC21550 detail comparison table?
Does UCC21550 can replace UCC21520 directly?
or any other solution can replace UCC21520? thanks
Hi Vignesh,
Interesting. Do the waveforms show some effect from this? Have you tried a higher turn off resistance?
I am curious about this due to the gate driver's lower turn off output resistance which allow higher sinking currents.
Regards,

Part Number: UCC21520-Q1 Hello,
Good day.
Our customer said this transient model is damaged, they downloaded the file and found it can't be used.
Could you please help check if this file is ok, and could you give a instruction for using the model…
Part Number: UCC21520 Other Parts Discussed in Thread: LM5039 , UCC28083 , UCC21550 , SN6501 , UCC28086 Hi,
I want to design an isolated half bridge converter 400VDC to 500V AC. The IC of interest is the UCC21520 - isolated dual-channel gate driver evaluation…
