TIDA-01606: Reg Topology of TL431/LM431 used in the Gate driver card

Caliber

Part Number: TIDA-01606
Other Parts Discussed in Thread: LM431, TIDA-01160, , TL431

We have chosen isolated boost supply for gate driver with reference to TI Design
(TIDA-10606 Gate Driver), Attached the TI Reference schematic

In the design, LM431 have been used to maintain the regulated output at -5V

Could you please address the following are the queries

1) We did not find any reference design (other than TIDA-10606) with LM431 regulator in topology.
   Capacitors (C1) are connected in parallel to its series resistor (R1) of LM431 circuit. Turning on or changing the
   voltage does not completely limit the current through the regulator because the series resistor has
   a parallel capacitor. A fast voltage rise will allow a current greater than the maximum according
   to the manufacturer's definition.

2) Share application note or the test report for TIDA-10606 Gate Driver

3) Circuit is simulated in Tina, observed oscillation during startup and
   continues with a small oscillation later on.

Hi,

I have a few clarifying questions.

Do you mean to say TIDA-01160? (https://www.ti.com/tool/TIDA-01160)
1. There is no TIDA-10606 and TIDA-01606 is a reference design for a solar power inverter.
Where is the LM431 in the reference design?

Let me know these so we can get on the same page and proceed with the process.

    Response : Sorry for the Typo error, it is TIDA-01606.

2.Where is the LM431 in the reference design?
    Response : Please refer the attached image where LM431/TL431/Adjustable Precision Zener Shunt Regulator is marked as U1 and highlighted in RED.

This image is taken from the gate driver schematic file of TIDA-01606 available at below link for the reference:

Thanks for the clarification!

It looks like this design was made by another group. Let me get them on this thread so they can answer your question better.

Hi,

We have tested this gate driver board along with the power stage and we have the results for the converter. We do not have any app note, Tina Model or test results specific to this gate driver card. We have only results for the power converter.

Hello Harish

Thanks for your response

Can you please share the test results for the power converter and the switching pulse of the power device

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
