Part Number: TPS51285A Hi Sir
My customer design TPS51285A in their project.
but currently find sometimes will find VREG3 no output. form circuit, i find the VREG3 output capacitor is 1uF. it is less than recommend 4.7uF.
May we pls also help check the…

Hi ,
According to TPS51285A datasheet suggestion , a ceramic capacitor with a value of 4.7 µF or larger (X5R grade or better) is required for each of VREG5 and VREG3.
If I change…
Part Number: TPS51285A Hi expert,
Customer has a question on CCM --> DEM. Below is the waveform that TPS51285A cannot get into DEM mode, we think it is due to wide ZCD threshold.(inductor current is down to -15.6A but it is still in CCM) Would you kindly…

Tool/software:
Hi team,
customer want their switching deadtime could be larger than 10nS spec,
I know it's related to MOS Qg as well, but since it's fixed.
is there…
Part Number: TPS51285B Other Parts Discussed in Thread: TPS51285A Tool/software: Hi,
Doe TPS51285B current trigger to OCP set point will protect immediately?
Or it allow a short period over OCP set point? If yes, what is the time period. thanks!

Part Number: TPS51285A Hi team,
1. Is VUVP-ST (UVP trip threshold at STARTUP) applied at soft-start duration? Or other condition? Please let us know the timing condition that is to be available.
2. It is presumed VUVP-ST to be available in typically 1.1ms…
Other Parts Discussed in Thread: TPS51285A I am using a TPS51285A for a 5V/3.3V regulator.
The enable inputs (EN1 and EN2) are connected to the VREG3 (3.3V LDO) output which becomes active when the input voltage reaches about 4.6V.
This works OK when the…
Part Number: TPS51285B Other Parts Discussed in Thread: TPS51285A Hi sir,
The input is 12V, EN1 / EN2 is controlled by LDO3 in my design,
I see that there are some time requirements not specified in the time sequence in the datasheet of Figure 4. TPS51285A…
Part Number: CSD87335Q3D Other Parts Discussed in Thread: TPS51285A , CSD87330Q3D , i have designed a 3.3V/5V converter using TPS51285A.
i have selected CSD87330Q3D for the design. input voltage is 8.4V -12.6V. output current is 15A. OCP value set as 18A. Inductor…
