Hi Ritesh,
Ritesh Prajapati said: Our external supply having 1 to 12VDC, 10A capability, so it should be sustain.
If there is a case that input voltage is down than suggest us the input voltage and current range for the external supply, so we can test…

Part Number: TPS61178 hi TI,
The inductance squeaks during the use of the customer. After the resistance of FREQ / SYNC pin is changed from 300K to 100k, the inductance squeaks disappear, but the output power drops. Please help analyze the reason. The…
Hi Sonali,
Sorry I wrote the wrong formula.
The frequency is around 500kHz (the Rfreq=316k) and the duty is 1-Vin/Vo=0.163
The current ripple Δi=Vin*d*Ts/L=1.07A.
The right formula is
We get the peak current formula Ipk=0.8+1/2=1.3A.
Best Rega…
