Part Number: TPS40322 Hi E2E,
Could you kindly let us know how to calculate the resistor of remote sense? Is it simply Low-Pass filter?
If the resistor is too large, maybe 200~300k ohm (wrong component on PCB), Does VOUT will reach for OVP because RemSNS…

Hi Experts,
Sorry for selecting wrong part number,the correct part number is TPS40322!
We encountered two phase non-balance isse at start-up, The one of phase would damaged caused by non-balance phenomenon
The one would operate BOOST…
Part Number: TPS40322 Hi E2E,
Our customer want to TI have the test to prove the EVM can PASS bode Plot as below conditions:
Phase margin > 50 degree
Gain margin < -20dB
Bandwidth range of 20%FSW~30% FSW
Could we have document about it?
If no…
Part Number: TPS40322 Hi E2E,
We use TPS40322 2-Phase solution and find VFB will from 0.6V rising to 0.606V when heavy load.
We also use fan to cool down the IC , but no any improve.
Did you have any idea to fix this issue?
Part Number: TPS40322 Hi there:
I'm helping customer to run the thermal simulation for TPS40322, but we can't execute the this in Webench.
Could you help us to check that? or helping us to provide the simulation data for customer condition
