TPS630242: Didn't get constant 3V3 output in Tina-Ti!

Part Number: TPS630242
Other Parts Discussed in Thread: TINA-TI

Hi there,

For our project, We selected Buck-Boost converter (TPS630242) for getting constant 3V3.

Battery voltage is 2.5V to 4.2V(1S1P). We simulated TPS630242 with the help of Tina-Ti.

When simulating, We get 3.4V instead of 3V3.

Hereby attaching the simulation circuit and its result.

Thanks & Regards,

Hi Sneha,

i did a simulation using Pspice for Ti and result is attached. output voltage is correctly 3.3V in heavy & light load.

actually, here is a voltage drop in your attached result, could you help have a double check?

I didn't put any load across the converter.

After putting load, I got constant 3V3 voltage for 2.5V to 4.2V.

Thanks for your help!

Hi Sneha,

seems i did not offer any effective help at all. thanks for your work.
