Part Number: LMG5200EVM-02 Other Parts Discussed in Thread: LMG5200 Hello,
While testing the board at switching frequencies (1 Mhz and 10 MHz) with variable load resistor of 0 to 36.3 ohms, the high side GaN Mosfet failed. I measured the input impedance…
Part Number: LMG5200EVM-02 Other Parts Discussed in Thread: LMG5200 Dear Master,
I use LMG5200EVM-02 to verify 5Mhz but waveform become very strange and efficiency down to 84%(original all over 92%).
Dut to I need to verify differently inductor,the test…
Part Number: LMG5200EVM-02 Other Parts Discussed in Thread: LMG5200 Hi
i try to operate the LMG5200EVM-02 but there is no output signal.
the output load is resistor of 47 Ohm.
On step 1 : I Connect a Supply to J3 Connector (6V).
On step 2 : I Connect …
Part Number: LMG5200 Hi Team,
A customer would like to know the difference between the LMG5200EVM-01A and the LMG5200EVM-02? As far as I can see, they are the same and I couldn't find any differences.

Hi Tosi,
For V3, you will be connecting it as show in the LMG5200EVM schematic shown in the user's guide ( https://www.ti.com/lit/ug/snvu551/snvu551.pdf?ts=1643211241238&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FLMG5200EVM-02 ). V3 will…
Hello Danilo,
For buck converter application, the LMG5200 EVM could be a good starting point. https://www.ti.com/tool/LMG5200EVM-02
For such a low output voltage, some topologies such as half bridge with current doubler can be considered.
We have a reference…

I'm trying to select an appropriate Boost Converter for a new product design. The design input uses…
Thank you for your reply. I can satisfy the requirements you said. This is the D-class power amplifier schematic I designed with reference to the LMG5200EVM-02. If I replace the LTC6992 with the TPA3116D2, this amplifier can better implement the power…
Thank you for your reply.
Thank you for your reply. But my problem should not be solved, I can meet the requirements you said, my PWM modulator output PWM is 0V and 5V. Regarding the design of the dead time, I refer to the dead time setting in the LMG5200EVM…
Hello,
Since you mentioned that 5V was applied and then 15V was applied, have you ever successfully supplied the voltage at 5V when there is no VIN? It looks to me the driver is damaged to lead to such a high supply current. The 5V supply current for…
