Part Number: TPS561208 Other Parts Discussed in Thread: TPS54320 , Our end customer asked to relay a question. They used the TPS54320 on a previous design, and like the TPS561208, the absolute input voltage is 2-3 volts above the recommended maximum of…
Part Number: TPS54320 Other Parts Discussed in Thread: TPS54620 The TPS54320 is out of stock. Can the TPS54620 be used as an alternate without any circuit changes?
Part Number: TPS54320 Dear Sir
Attached Schematic. The fault phenomenon is PH pin short ciruit with GND.
Our Vin 12V ,Vout 5.1V，Iout 2A .
We test about 60 pcs and failure about 11 pcs.
Could you help me know the reason,many thanks!
Part Number: TPS54320 Other Parts Discussed in Thread: TPS54620 Hi Team,
My customer is searching buck converter which could sink/source current.
Input : 10.8V-13.2V
output : 5V-9V
sink/source current : 1.5A
I found TPS54320 could meet our requirements…
Part Number: TPS54320 Hello team, I am considering how to use TPS54320 1MHz external clock to decide switching frequency. I designed below block diagram. During power on, I set IO of FPGA IO as Hi-Z and TPS54320 power on by internal clock set by RT(56k…
Part Number: TPS54320 Hi Expert,
I saw the sink current limit show in Electrical Characteristics table of datasheet page 6, could you share more the sink current behavior and what's the condition to trigger sink current protection?
Best Regards, …

Hi TI team,
I am using TPS54320 with the following condition.
Vin = 8.5V、Vout = 7.2V、L = 4.7uH、RT= 68k(Fsw = 714kHz)
We tested with Iout = 3A and below is the waveform
Green: Iout Yellow: Vout Cyan:Vsw
It turns ON(40ms) and OFF…
Part Number: TPS54320 Hi,
We are using TPS54320 to step down a 12V input to 1.8V with a 1A nominal load.
Both TI WEBENCH ® Designer and our loop test result show we have enough Phase and Gain margin.
While the 1.8V will randomly power off, it seems…
Part Number: TPS54320 Hi Team.
When Vout line is short circuited to another power line, TPS54320 broke. Vin and PH terminals are short circuited.
Vin = 5V Vout = 3V another power = 4.7V
I want to know the reason of I/O short. This does not applicable tha…
Part Number: TPS54320 Hi team.
I have a question about mounting evaluation.
Is there the recomended condition of solder connection of thermal pad to signal ground ? What is the percent of the recomended condition of solder connection?
