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.
Rail 1, 1.8Vout/23…
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

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?

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…
