Part Number: TPS54338 Other Parts Discussed in Thread: TPS564257 , TPS562212 , TPS54295 Hi team,
TPS54338 has been damaged (burned out). We are currently unable to identify the root cause and would appreciate your support. We will attach the schematic…
Part Number: TPS54338 Other Parts Discussed in Thread: TPS543321 Tool/software: Dear Team
TPS54338 is used as the main Buck power in my design. The design detail is as follow:
5V input, 3.3V output. There is an about 8KHz ripple on the output, whatever…
Part Number: TPS54338 Hi
We are considering to use tps54338 as an inverting buck boost. But, we are a bit worried that theres no option for external compensation. Do you have any infortion regarding using the converter chip as inverting buck boost?…
Part Number: TPS54338 Dear Team,
My customer is evaluating the TPS54338 on their board. When they measured the SW pin waveform, the priod when the SW fell below -0.3V was about 11ns, and the lowest SW voltage was -1.64V.
<Conditions> - VIN: 4.75V…
Part Number: TPS54338 Tool/software: Hi,
I'm designing a PCB using the above TPS54338. This SMPS takes 14.5V as input, and outputs 3.4V, which is then powering the MCU and a ADP5076 dual boost converter. Since this PCB has sensitive analog signals on…
Part Number: TPS54338 Tool/software: Hi Team,
Based on the data sheet, I calculated the switching frequency in 6V to 5V is about 1.4M, could you please check below calculation steps and help test on the EVM board?
Duty cycle: 6/5V=83.3%
Minimum…
Part Number: TPS54338 Tool/software: Dear Team,
My customer is considering to use the TPS54338 with external clock synchronization. And this 1.9MHz external clock has frequency spread spectrum as follows,
- External clock: 1.9MHz +/- 2% (max), +/…
Part Number: TPS54338 Tool/software: Dear Team,
My customer considers to use the TPS54338 with both RT mode and SYNC mode. Datasheet, page 16 to 17, "6.3.5 Switching Frequency Selection / Synchronization" describes the RC circuit "Figure 6-3. SYNC Mode…
Part Number: TPS62175 Other Parts Discussed in Thread: TPS62932 , TPS54338 , TPS62933 We are using TPS62175DQCR in our design for 20V → 2V buck conversion. Due to supply constraints, we are looking for a drop-in replacement with the same WSON-10 footprint…
