Part Number: TPS62130A
Other Parts Discussed in Thread: TPS62135, TPS62130

On the datasheet , it is mentioned as the following ;

[As long as the output is below about 0.5V a reduced current limit of typically 1.6A is set internally.]

How much is the variation of the reduced current limit(1.6A typ)?

This is not specified, so we should assume around +/- 50%. Is this important for your application?

As well, we have the newer TPS62135/6 which offer smaller solution size, more features, and a more accurate output voltage.

Hi

Could I ask one more question?
Is that current limit(1.6A typ) applied at start-up as well?

Because that current limit is concerned by load current of TPS62130 when it start-up.

Yes, this is stated on page 10.

Most loads cannot draw current when they have insufficient supply voltage.
