Tool/software:
New project, BUCK circuit (asynchronous), bus voltage DC310V output DC110, MOS transistor driven by pulse transformer, can the pulse transformer drive in Figure 1 be used? In addition, DCL and SFRA use their own designed boards?
thank you!

Hi Liujun,
The EG27324 is not a TI device so we cannot speak to the capabilities of that specific device. If it accurately accepts the PWM signals from the C2000 microcontroller and matches your power specifications, it should be fine.
The DCL and SFRA are both software so they don't require any separate boards. But Digital Control Library (DCL) will not work on your device because of the lack of FPU on the TMS320F2803x device. You should look to consider one of our newer devices which support the DCL, such as TMS320F280013x, TMS320F280015x, or TMS320F28002x.
Likewise, SFRA should only require UART TX and RX connection from the device to the host computer

Hi Peter Luong1
Do you have pulse transformer drive circuits and pulse transformer drive chips?
How to prevent VGS misguidance caused by VDS of MOS transistor when using pulse transformer to drive MOS transistor?
Can UC1707 be used to replace EG27324?
thank you!
Hi Liujun,
Let me reach out to some other experts for their feedback on this question, please allow some time for them to get back to you. Thank you

Hi liujin,
Please view this app note for using gate drivers in transformer applications: https://www.ti.com/lit/an/slla602/slla602.pdf
We have the UCC27324, which is a pin-to-pin replacement to the EG27324 (if you're not using that SD pin).
Thanks,
Rubas
