Here is more detail. We are using the TPS54561 DC/DC as the main supply in our system. We want to sync it to the AR1642 clock to control the spurs. The TPS54561 is sensitive to the output impedance of the driving clock while it is idle during startup…
Other Parts Discussed in Thread: TPS54561 , TPS54060 Hi, I would like to design an inverting power supply to generate a -24V @ 4A from a Vin of 24V.
My thinking is to use the TPS54561 according to the application note SLVA317B . but before I am continuing…
Part Number: TPS54561EVM-555 Other Parts Discussed in Thread: TPS54561 The TPS54561 is intended to be used to both provide 6.9VDC at 3.5 Amps and also charge a 6 Volt Sealed Lead Acid battery.
The switcher circuit is replacing the regulator section…
You may be close to the maximum duty cycle and power dissipation of the TPS5450, especially at low Vin and max current of 4.6 A. Can you post your schematic and layout? You may also want to consider TPS54561.
Hi Murray, Thank you very much for your quick response. I very much like the proposed chip. We will evaluate purchasing the EVM. Surely addition to the GSM modem I must also supply a XBee modem. I need to provide in this instance up to 5A peak. Can you…
Part Number: TPS54560-Q1 Other Parts Discussed in Thread: TPS54560 , TPS54561-Q1 Hi Sir
we use TPS54560 in Vin 12V/Vout 5V 2A.
we follow the EVB circuit, but find vout voltage will turn on first then turn off. then turn on first. then normal on. …
Hi Darryl,
Thank-you for the reply. Good idea to monitor 0X3B equalizer status. With what we are testing now, it is not changing. We’ll keep an eye on it. That should tell us something about forward errors or signal integrity, if they reappear.
Meanwhile…
Hi Green,
I would recommend connecting Slave Comp Pins through a buffer from Master Comp Pin. I am sharing a schematic design made especially for interleaving applications as yours.

Hii Onkar,
I have attached the sheet and below is the Section of schematic for reference,
Also I have tested this circuit with Cout : 132 uF and 176 uF but same behavior is there.
