Part Number: TPS543320 Hello,
can you please confirm that TPS543320 is compatible with fly-buck operation? I use the part already on the board, and I'm in need of some +- voltage rails for op amps. The part is forced PWM, the negative inductor current…

Vin=12V and Vout=1.2V @2.5A . please give feedback on the above design
Hi Ramkumar,
If your application is 12Vin, 3.3Vout/3A with Ta=85C, I would recommend TPS543320.

Webench selects an inductor that has an Isat that is lower than the TPS543620 current limit.

The low setting for current limit is 4.5A for TPS543620. The Isat of the inductor must be greater than 4.5A. Using a 6A rated device for <100mA is not optimal.
The TPS543320 is the 3A pin to pin version of TPS543620, it has current of 3.3A, lower…

I am looking for an alternative to the LTC3601EMSE#TRPBF. Does TI have something (preferably pin to pin) for this device? Nothing was coming up on the cross reference tool…
Hi Jeff!
You want peak inductor current be 4A right? What is the maximum output current of your application? Could you pls take a look at TPS543320?

Hi Thomas,
If I understand your requirement about VIN hysteresis ON/OFF, then this is a standard feature in many of our converters.
Please read the paragraph " 7.3.2 Enable and Adjustable UVLO" in :
