TMS320F280049: TIDA-010086 performance Data

Jack Li-SH
Expert 3675 points
Part Number: TMS320F280049
Other Parts Discussed in Thread: TIDA-010086

Dear sir,

 My customer is interested in our TIDA-010086, and now they want to ask for more detail data to check:

1. the loop test - loop bandwidth and phase margin

2. the output noise @ 20Hz to 20MHz

3. The load regulation

Would you please help on it?

By the way,  whether we can share the demo code with customer?  If okay,  would you please send it to jack-li@ti.com.

Nice day!

Regards,

Jack

    Hi Jack,

    • The constant current loop bandwidth is ~180Hz at 16ksps control loop frequency. Please check the figure 3-8 in the design guide https://www.ti.com/lit/ug/tiduey0/tiduey0.pdf
    • For load regulation data, please check tables 3-2, 3-1 and 3-2 in the user guide.
    • Noise: We have not done noise test. The main source of the noise is switching noise. The measured output current ripple is less than <10mA. The sampling frequency will also introduce noise in the system but it will be much smaller than DC/DC noise.
