Hello Masazumi,
Thank you for the interest in the UCC27714 and UCC27511 gate drivers. In most designs the gate resistance is selected to achieve the desired switching times of the MOSFET in the application. The driver output current will be determined…
Other Parts Discussed in Thread: UCC27511 , UCC27519 , TPS2828 Hello all
I'm trying the drive IPP60R099C7 power mosftet in PFC boost stage with Switching frequency equal to 125kHz. . This Mosfet Qg is 45nC and I believe either UCC27511, UCC27519 can…
Hello Senthil, I appreciate your sentiments. Those older schematics are beautiful, however they are only available as pdf. Presently TI uses Altium for EVM's and Reference Designs. Here is an example. UCC27511 4A/8A Single Channel High-speed Low-side…
Hey Chase,
Thank you for reaching out to TI with your questions regarding the UCC27519A-Q1.
Please see the attached Schematic Review Template for reference.

Here are a few notes:
1. The EN pin can…
Regarding the measurement specifics:
The Tester for Switching times is a clamped Flyback topology. Components use are as follows:
-Drain Inductor is 1uH/100A Drum Core.
-Clamping Diode is a 10A/100V Schottky in D-Pak package.
-Driver IC is UCC27511…
Thank you Daniel and Ulrich. The output is general purpose, so unfortunately I don't know exactly what the end customer will connect it to or use for cabling. I do know the load impedance will be 50 Ohms and is 0 to 5V PWM. The rise/fall time spec probably…
Hello Minami-san,
I am unsure if I can confirm the ESD spec of this device, but I can investigate further if needed, but before I do I have a few questions.
From our previous thread :
Is there any reason for using this device (as the original…
Hi Max,
Thank you for inquiring about our driver, my name is Mamadou Diallo and I will help address your concerns.
This current is specified by design and 300uA is just the absolute max or corner case. In reality, it is typically less than that as…
