Part Number: TPS54260 Hi, I am currently using the old "DCDC_TPS54x60_CALCTOOL_v1.xls" provided by TI to design a TPS54260 power supply. I was just wanting to confirm what the 'lf' value represents on row 137 of this calculator? It looks like it is just…
Part Number: TPS54260 Hi
We had our PCBA manufacturer fit the wrong resistor to the RT/CLK pin 28K instead of 287K.
I understand this would put the switching frequency well over the maximum.
It appears the the chip is running in eco-mode and the output…
Part Number: TPS54260 Dear team,
I want output 5V but it is geting 4.6V. what is issue?
pleas check below schematic for different test point voltage.

Part Number: TPS54260-Q1 Other Parts Discussed in Thread: TPS54260 Hi Team,
The customer is trying to change a Schottky diode(NRVTSS3100ET3G) to new one due to EOL. Please check the questions below and let me know.
(Vin=24V, Vout=12V, Iout=1A to 2.5A) …
Part Number: TPS54260 1) How to calculate the minimum voltage, vstart and vstop?
In my case, I have R1 = 80.6k; R2=348k; VENA=1.25V; I1=1.18A and IHYS=3.35A
80.6e3=1.25/((x-1.25)/348e3)+1.18e-6
This way, I calculate Vstart = 6.647 and Vstop = 6.37, correct…
Part Number: TPS54260 Our Schematic as below:
When I test Load Transient,result is bad:
After I remove L2,result is ok:
Vin is varing when with L2,so I want to know
1. If Vin must keep stable when test Load Transient?
2. And how can I deal with Vin…
Part Number: TPS54260-EP Other Parts Discussed in Thread: LM5012 , LM5013 TPS54260-EP Buck Converter maximum input voltage range is 65V.
In our design, TPS54260-EP placed after TVS diode.
While performing lightning test , will get around 90V after TVS diode…
Part Number: TPS54260 Hello - I have an architecture that uses redundant buck converters to power a common 3.3V node. In one scenario we remove the input voltage to the TPS54260 - and power the connected output via another supply. In this scenario, the PWRGD…
