Part Number: TPSM84A22
we use the TPSM84A22 to provide 1.39 V at maximum 8A rail in our system. Please see the sch:
the total output capacitance is 141uF ( 3x 47uF ceramic) plus 0.1uF as seen above.
Note : the inductor seen in the PI filter at the output…
Part Number: TPSM84A22 Hi,
I am trying to analyze the stability of TPSM84A22 power module.
[1] Is there any average model available? This can help in drawing bode plots and closed loop output impedance curve.
[2] Is there a way to do bode plot simulation…
Part Number: TPSM84A22 Hi,
I am using TPSM84A22 in my design for 1.9V at 10A. I used web-bench for the circuit design.
I have some doubts:
(1) The switching frequency is fixed at 4MHz. What is the crossover frequency? Does it vary with different Vout…
Part Number: TPSM84A22 HI TI Team,
Can I leave power good pin (PGOOD) floating if power good functionality is not required? What does TI recommend?
Thanks,
Binayak
Part Number: TPSM84A22 Other Parts Discussed in Thread: TPSM84424 Hi TI team,
I'm using the following regulators of TPSM family in our upcoming board.
TPSM family: TPSM84A22: 1.9V@10A TPSM84A22: 1.5V@10A TPSM84424: 1.8V@4A TPSM84424: 3.3V@4A TPSM84424…
Part Number: LMZ31710 Other Parts Discussed in Thread: TPSM84A22
Hi, In the datasheet of LMZ31710, it is told not to connect AGND (analog ground) with PGND (common ground) because they are connected internal to the IC.
[1] What are the reasons for recommending…
Part Number: TPSM84A22 Hi,
I have seen in the datasheet some EMC test results of the componant p.21 of the pdf. I would like to know more about the test conditions:
Is the output load was "just" a passive resistor, or an active load ?
Is there…
Part Number: TPSM84A22 Hi team,
My customer tested our EVM board with VIN 12V, Vout 1.8v, load 10A, no fan, ambient 95°C, and find the device will trigger thermal shutdown.
You know the module's performance will change based on the device variation…
Part Number: TPSM84A22 Other Parts Discussed in Thread: TPSM84A21 The data sheet states that this module "Meets EN55022 Class B Emissions". Is there a graph available showing the Radiated Emission Performance?
Also, where can I find the footprint…
Part Number: LMZ22010 Other Parts Discussed in Thread: TPSM84A22 , TPSM84A21 , LM317 , LMZ14203H , PTN78020W Is this LMZ22010 module a fair candidate for a programmable supply via pot, I2C pot, DAC, etc.?
