We use TPS61230A under the following conditions.

Vin=3.0V

Vout=3.3V

Iout=1.6A

If input voltage is 3.8V, How is the IC?

Is the IC broken?

We want to know the operation that Vin ＞ Vout.

Best regards,

When Vin=3.8V, the IC will not damage. as 3.8Vin is about 0.5V higher than the 3.3Vout-Set, so vout can't be regulated at 3.3V anymore, Vout is nearly equal to Vin in this case.

For this your application, i would suggest TPS61021A or TPS61230, TPS61280D with support VIN>VOUT. the TPSP61230A can't support VIN higher than VOUT. it is not damaged, but enter a special mode which we don't suggest customer to use.
