Part Number: TPS54917
Hi SIR
We use tps54917 to design 3.3V to 1.0V_9A power supply for asic use.
A phenomenon was found during the measurement.
As long as the inductor current enters the continuous conduction mode (about 1A),
Low Side Mosfet_Vds shows…
Part Number: TPS54917 Hi Expert,
When customer test tps54917, they see a ~40Khz oscillated frequency at Vout in no load. Also, they observe the oscillation frequency would change if C4 changed. Do you have any idea about it?

Part Number: TPS54917 Hi Expert,
I have a question that when we measure bode plot and see gain across zero not only one time, shall we measure 1st or 2nd point for phase margin?
For example we did test on TPS54917 with Cff=680pF and see 1st Fc=28K and…
Part Number: TPS54917 Hi E2E.
Could you share Compensation Calculator Tool for TPS54917?
Our customer would like to use this part to design.
Maybe you can review the circuit first!
Vin= 3.3V, Vout=1A / 8A
Other Parts Discussed in Thread: TPS54910 , SWITCHERPRO , TPS54610 , TPS54917 The datasheet is rather lacking in explaining many of the component value selections. Usually power supply datasheets have formulas for computing output capacitance/inductance based…
Other Parts Discussed in Thread: SWITCHERPRO I would need to change the switchingfrequency to see how efficiency changes. But today I can only temporary change the frequency to see the gain/phase plots. Would love to also be able to set the switchingfrequency…
Other Parts Discussed in Thread: TPS54917 , SWITCHERPRO if I make a design 3.0V to 0.9V 3A using TPS54917 I get a warning that minimum ontime is violated. This happes as the default frequency is 1.6MHz. but there is no easy way to change the frequency to…
Hi,
We are releasing next version of SwitcherPro on January 30th, 2009. TPS54617 is included in there. Please use TPS54160 or TPS54917 in the meantime as a replacement.
