Part Number: TPS549D22 Other Parts Discussed in Thread: TPS548B22 , TPS548D22 Depending on the available supply, customers may ask if they can use PMBus parts such as the TPS549D22 or TPS549D22 in place of their pin-to-pin counterparts that lack a PMBus…
Part Number: TPS549D22 POINT 1
Customer wants to change the voltage setting in the internal NVM.
The DS states:
It is permitted to use the STORE_DEFAULT_ALL command while the device is operating. However, the device may be unresponsive during the write…
Part Number: TPS549D22 Other Parts Discussed in Thread: TPS54678 Hi team,
For a design my customer is planning on implementing the TPS549D22 switcher. They have simulated the load transient response with the Webench tool and changed the inductor & capacitance…
Part Number: TPS549D22 Other Parts Discussed in Thread: TPS546D24A , I have a customer asking about the drive capability of the device for I2C.
They want to pullup PMB_DATA and PMB_CLK lines to the supply (3.3V) via a 1kΩ resistor. This means the pins have…
Part Number: TPS549D22
What is the "best practice" for unused PMBus pins? (PMB_CLK, PMB_DATA, SMB_ALRT#)
In the following post, the answer was "they can be left floating" https://e2e.ti.com/support/power-management/f/196/t/711485?tisearch…
Part Number: TPS549D22 Hi Team,
What's the maximum current consumption of VDD pin of TPS549D22 when converter is switching? We need to this data to select correct input filter resistor power rating. thanks.

Part Number: TPS546C23 Other Parts Discussed in Thread: TPS549D22 , TPS548D22 , Hi team,
When I tested DS waveforms of TPS546C23 and TPS549D22, I found some differences. Why the DS waveform of TPS546C23's high/low side switch is different from that of TPS548D22…
Part Number: TPS549D22 The DS show the output voltage can be programmed from 0.6V to 5.5V. May i know we how to program the voltage at 3.3V and 5V? Thanks.
