Part Number: TPS54424 Hello,
EN pin source current is 1.2uA when Ven = 1.1V and 4.8uA when Ven = 1.3V. There is a word, "hysteresis".
Does this mean EN pin source current is switched between 1.2uA and 4.8uA? If so, 1.2uA while rising and 4.8uA…
Part Number: TPS54424 Output Ripple Question
Datasheet July 2017, Output Ripple Fig 43. Is this using Circuit Fig 35 with output filter?
I plan on 200KHz sync frequency and SER1360-103KLB 11mOhm 10uH inductor optimized with WebBench.

Part Number: TPS54424 Hello,
My customer has question About TPS54424 Pre-Biased Startup time,
How long is the prebias start-up from when EN goes high until output voltage starts to be output?
The graph is shown in Figure 50 of the data sheet, and it…
Part Number: TPS54424 Team,
I have a customer getting ready to begin a design with TPS54424, and they have asked if we have any tools available for helping with the calculation of the loop compensation for the device. Can you point me to the best tool…
Part Number: TPS54424 Other Parts Discussed in Thread: TPS53513 Hi all
I'm using this TPS54424 chip. Please check the schematic design. Thank you for your help
Part Number: TPS54424 Hello team,
I have a question about TPS54424 internal oscillator architecture. The RT/CLK pin is connected to the internal block of "Oscillator with PLL" from the datasheet. When we use RT mode, the external resistor can…
Part Number: TPS54424
Team,
I have a customer using TPS54424 in a design, and they wish to utilize an LED as an error indicator in their schematic. The issue here is they wish to use a pull-up resistor low enough to provide sufficient current to the…
