Part Number: UCC27200 Tool/software: Hi,
I am working on a boost converter using push pull topology to drive my UCC27200 mosfet. I want to boost a 24V DC battery to 380V using a 100KHz transformer. I am driving my PWM using a C2000 lauch pad and with…
Other Parts Discussed in Thread: UCC27200 Hi guys,
I want to use the UCC27200 in a synchronous boost converter. My high side of the gate driver would be wired to the mosfet that is inline with the inductance and takes office of the diode and the low…
Part Number: UCC27200 Other Parts Discussed in Thread: UCC27201 Tryong to use the UCC27200 in a synchronous buck converter with the TPS7H5001. Getting no outputs from the gate driver.
The inputs at the gate driver from OUTA and SRA both toggle, but…
Part Number: UCC27200 Other Parts Discussed in Thread: UCC27282 Hi team,
If I have several gate drivers of UCC27200, the input of these UCC27200 are all from the same PWM signal.
Due to the delaying matching, it might be have inconsistency of these…
Part Number: UCC27200 Hello!
I would like to use the ucc27200 as a bridge synchronous rectifier driver on the secondary side of the phase shift.
Therefore, the HI and LI pins receive in-phase signals instead of anti-phase signals.
Is it possible…
Part Number: UCC27200 Other Parts Discussed in Thread: UCC27201 Hi There,
We are trying to get output PWM's at the HO pin of UCC27200. We have followed the application implementation guide but still we are not getting any output.
We also tried soldering…

Hello
In July I asked this issue and continuously we tried to improve. We have continued test torepeat over 100 times ON and OFF.
Now recent phenomena is, gate driver have been broken…
Part Number: UCC27200 Other Parts Discussed in Thread: UCC27282 , Dear Team,
Here is Kevin from Delta Taiwan team.
Do we have high low side driver with a maximum 5V rating here?

Dear Richard
Thank you for your quick reply.
Attached is simplified schematics of Active clamp, especially primary side.
Please refer to Fig 2.
Behavior of the UCC27200 when reached broken, VDD to GND is "short condition".

Hi, 1. For Active Clamp, please answer that it is normal behavior that the phenomenon of duty increase and Vds voltage rise occurs when the power is shut down.
Yes, this depends on the VCC UVLO off or line UVLO off instant and the device has no function…
