Part Number: TPS54331 To set the slow-start time (tss) of the TPS54331 within the range of 1ms to 10ms, a 22nF capacitor (Css) was connected between the SS pin and GND. The calculated result, based on typical values from the datasheet, was 8.8ms, however…
Part Number: TPS54331 Hi team,
My customer encountered an issue about TPS54331, the SCH is as below:
In their trail prodcution process, they found part of board(7pcs in severval hunderd pcs) can't power up normal, the input voltage and en voltage…
Part Number: TPS54331 Tool/software: Hi
We recently using TPS54331 for designing 24V to 5V DC-DC converter. I try to simulate the Transient simulation in Altium Mixed Simulation, but it always fails. I used the simulation model provide in TI website…
Part Number: TPS54331 Hi Team,
Currently customer met application issue with a new batch TPS54331:
Output ripple will be bigger, 3 times
Confirm the issue appears under light load condition, increasing load, issue can disappear. Seems burst mode…
Part Number: TPS54331 Tool/software: I am using the below circuit
J1 is Open
I an getting the following wave at the output.
What could be causing this variation ?
I tried changing C17 and L2 but it didnot help
Kindly suggest
Part Number: TPS54331 Tool/software: I am using the TPS54331 IC to convert 5 V input into a 3.3 V output. I am using the schematic as designed in webench. I am simulating on LTSpice.
However, when i give a 5 V input, I am getting an output of 2.9 V…
Part Number: TPS54331 I am using a TPS54331 step-down (buck) chip with an input voltage of 12V and an output voltage of 5V. The expected output current is 3A, and the load is an LED light. When some of the LEDs light up, the 5V output has significant…
Part Number: TPS54331 Hi,
I want to perform some load transient simulations and play with overshoot/undershoot compensation techniques.
I am not limited to use the mentioned TPS54331, any other buck converter will be fine. I intend to use QSPICE…
