Other Parts Discussed in Thread: TPS51220 Dear Sir
For DS we see if SKIPSEL1 connect to GND, then TPS51220 will go into CCM mode. and will get worse efficient.
may we check if there have other disadvantage if we SKIPSEL connect to GND.

Hello, David,
ok, I understand your mean.
I explain to you using below figure. The positive direction of current is shown as figure.
a: when Vout voltage is max to 5V, Vdac voltage is 0.
I1=I2+I3.
(Vout-Vfb)/R2=Vfb/R3+Vfb/R1 (1)
b: when Vout voltage…

We do not have a TPS51222 reference design, however the TPS51220 is very similar, with a similar pin-out. You can evaluate the TPS51222 on the TPS51220 evaluation board with some modifications.
In addition to switching out the controller ICs…

Part Number: TPS51220A Other Parts Discussed in Thread: TPS51220 Hi Experts,
About the Jitter of DCAP, I use TPS51220 to build 24V to 5V and 24V to 12V.
The jitter of 12V rail is around 290nS, the other channel, 5V, is around 165nS, Rcomp is 10K for both…
