Other Parts Discussed in Thread: TLV61070A
Hi TI,
I have a question in regards to a DCDC-Boost-Regulator configuration for the TPS61070.
Is it a safe operating mode, if VIN >= VOUT?
The question is related to an application requirement, where the input voltage can be either a 2xAA battery or a 5V input.
Since this is a low cost product, I'm wondering, if I could simply use the boost converter in this operation mode, without disabling and bypassing the DCDC Boost regulator.
I have tried it already and I see, that the input voltage is directly forwarded to the output. Therefor, the TPS61070 seems to switch permanently on the internal PMOS switch.
Is it a safe operatinal mode for the TPS61070? I think so, but please confirm.
What would be the maximum continous current for the internal PMOS, since only the peak current for 600 mA is given in the datasheet?
Thanks for your assistance
Christian
