Part Number: TPS62177 Other Parts Discussed in Thread: TMDS64EVM Dear TI Expert Engineer,
About the sleep mode pin of the TPS62177
See the data sheet
Only use normal mode
Question
Is it okay to leave the sleep pin open?
Or should I connect…
Part Number: TPS62177 Hi, We have a PCBA in a product that uses a TPS62177DQCT buck regulator to regulate 25V to 3.3V. Several of the regulators have failed on products and my team has been testing the PCBA to determine the root cause. We've measured…
Part Number: TPS62177 Tool/software: Hi,
I just got 10 PCBA using the TPS62177 coupled with the inductor IFSC1515AHER100M01. This inductor is recommended in the datasheet and it has no polarity.
The inductor has 100 stamped on it and when compared…
Part Number: TPS62177 The app notes and literature all have the EN pin connected to VIN. I would like to delay the ENable start up until VIN is greater than 9 volts. At what threshold and how much hysteresis does transition to EN on occur?
The sleep…
Part Number: TPS62177 Dir Sir or Madam,
on my board i use the TPS62177 and a STM32 Microcontroller.
I use the PowerGood of the TPS62177 to reset the µC.
The µC needs a minimum reset time of 300ns to reset correctly.
Unfortunately there is no…
Part Number: TPS62177 Other Parts Discussed in Thread: TPS62175 , We'd like to use the TPS62177 as a drop in replacement for the TPS62175. To make it as simple as possible, we'd like to leave the circuit for the TPS62175 in place, so FB would remain connected…
Koti,
Given your application conditions, changing the device is not going to make any significant difference in the result as your problem is inherent to your system architecture.
For instance, a 4mA limited 7V input supply can only provide 28mW …
Part Number: TPS62177 Hi
Please Provide me the Updated Full Material Declarations for the part TPS62177DQC as per the PCN 20210713001.1
The Material Content sheet of TI website having the MD for TPS62177DQC , but not sure whether it is updated…
Part Number: TPS62177
Team,
The use case is:
TPS62177 is powered off as there are no VIN source. However an other power source provide 3.3V to the TPS62177 SW and VOS pins (see pink arrow on picture below). I assume that the SW output and VOS input…
