Part Number: TPS51220A-Q1 Hi team,
Is it ok to use TPS51220A-Q1 to support below power rail spec?
1st TPS51220A-Q1.
Vin is 8-17V.
Rail 1, 1.1Vout/30A, MOSFET is NVTFS4C06N
Rail 2, 1.2Vout/25.8A, MOSFET
2nd TPS51220A-Q1
Vin is 8-17V.

Part Number: TPS51220A-Q1 Hi TI,
Regarding of TPS51220A feedback point(VFB) , datasheet figure 51 from Cout trace connection to R1 is normal routing layout guide. The mode is local voltage sense, if it's connection mode from R1 point change to end device…
Part Number: TPS51220A-Q1 Hi Team,
The TPS51220A-Q1 datasheet has denoted that the Vref2 pin should connect a 0.22uF cap to GND.
May I have your help to check that is there any side impact if the 0.22uF cap change to 1uF?
Hello,
I do not think there is Q100 that is direct replacement of this part. There is the TPS62872 this is a Low VIN device.
There is also a controller such as TPS5120-Q1, TPS51220A-Q1
thanks

Dear Mr/Mrs.
Here are to many questions about easy converter 511220A, it shows that something is wrong.
We have two identical fanless motherboards based on TPS51220A from 2016 in following configuration: …

The waveform you provided looks like it's operating at near 100% duty cycle trying to provide 11V output at 12V input. That's why you're seeing low switching frequency and very high duty cycle.
Is DC_IN 24V?
R66 seems pretty high at…
Other Parts Discussed in Thread: TPS51220A Dear Sir
As I know TPS51220A could design for 12Vout
I have few question
if we use it for single 12Vout power supply ,could I de-pop component for 5Vout power rail ??
If yes!! how could I do it ? Remove…
Part Number: TPS51220A Dear Team,
Please kindly help to confirm where my schematic needs to be modified, as +12V and +5V output phase low-side MOSFET(Q38&Q8) is always damaged.
what is the most likely cause of damage?

Part Number: TPS51117 Other Parts Discussed in Thread: TPS51220A Dear,
our client use RICHTEK RT8131B Buck PWM Controller for IPC application.
and we find TPS51117 maybe can replace RT8181B.
