Ganesh,
I can help address any specific applications support related to the gate drivers in your application.
The GaN power stage team might be suited to address your specific needs in which case you will post on a separate thread with the specific…
Thanks for sharing your insights and the test update! Some comments about the VIN instability issue. Not sure if it is related with the ground bouncing. Please refer to the LMG1210 datasheet section 9 for explanation. Besides, for this application, LMG1210…
Part Number: LM5046 Other Parts Discussed in Thread: LMG1210 Hi,
My customer would like use LM5046 to driver bothe Primary/Secondary side GaN FET, from secondary side we suggest LMG1210 to drive GaN FET but for Primary side can customer driver GaN FET…
Hi Shidara,
Thanks for reaching out about lmg1205 on e2e.
This circuit can be used for dead time eval or proto however it is prone to temperature variation.
The dead time circuit can be fine tuned by changing the R1 and R4 resistor values. This…
Part Number: LMG1210EVM-012 Other Parts Discussed in Thread: LMG1210 , UCD3138 The LG1210 Power stage has a capability of operating up to 50MHz.
But you give no indication of a PWM control that will take advantage of this high frequency.
Can you recommend…
Hi Sebastiano,
The LMG1210 has the same limitation and also needs to be updated. I am currently updating LMG1020 model to be floatable now however this is not a half bridge driver and is not representative of the LMG1210 or LMG1205. The TINA models…

Hi Taekyun, thanks for your post, welcome to e2e!! LMG1205 can gate a smaller MOSFET (and GaN) above 7MHz, also consider the updated cousin - LMG1210, which can switch faster with adjustable deadtime control. whats your application? whats the power level…
Part Number: LM5113 Other Parts Discussed in Thread: LMG1205 , LMG1210 , LMG1205HBEVM , , LM5017 Dear TI support team,
We are currently on a stage of firmware development for our own DC/DC converter based on dsPIC33CK256MP202. I’m using simple project…
Hi Gregg,
If it is a soft-switching topology, LMG5200 is not bad choice, and provide you easiness in layout. At hot temperture, Rdson of LMG5200 would approach 23mOhm. Even though you are doing Class D, if you drive only a resistive load, I guess you…
