Part Number: LM5143-Q1 Other Parts Discussed in Thread: LM5143 Hello Team
We are using LM5143 for one of our application . LM5143 is used in dual phase mode. WE wanted to know whether the PG1 and PG2 pins can be used separately. The idea is to monitor…
Part Number: LM5143-Q1 Other Parts Discussed in Thread: LM5143
In the application of LM5143 from 24V to 14.4V, when the temperature ranges from 0 to -30 degrees, the 14.4V output voltage fluctuates greatly. We hope to help identify the cause of the abnormality…
Part Number: LM5143-Q1 Other Parts Discussed in Thread: LM5143 Hi Experter,
We would like to change pull high resistor for LM5143 DEMB pin from 4.7K ohm to 47K ohm.
Could you have any concern for this changed. many thanks.

Part Number: LM5143-Q1 Hi TI expert,
May I know the definition of following PGx_xxHYST?
It represent the level when UV or OV condition is released?
And whether the PGx_OVHYST part is falling instead of rising.
Not quite understand the definition.
The…

Hi Team,
Kindly help here in verifying our circuit.
We are using the IC LM5143-Q1 in our design.
Specifications of our circuit is the following
Vin = 6V to 30V
Vout1 = 5V, 9A
Vout2 = 3.3V, 9A
The MOSFET that are connecting in…
Part Number: LM5143-Q1 hi team,
now customer use LM5143-Q1,meet a problem, this case is very urgent.
device work condition: VIN =24V, Vout=14.4v, the typ Iout=6A.
when customer enable the EN, the mos of Vout2 will breakdown.
of course customer test when…

Hi TI expert,
May I know whether VCCX in LM5143x-Q1 has any power sequence requirement?
I'm wondering if VCCX is powered before Vin, is there any side effect?
I notice from another post that the internal path has an diode…
Part Number: LM5143-Q1 Other Parts Discussed in Thread: LM5143 Hello TI Team
We are using LM5143 in two phase configuration.Based on the calculation we need a total output capacitance value of 440uF (considering degradation).
So 2 x 220uF is placed at…
