Part Number: TPS61088

Hi,

Could you tell me about TPS61088 operation in "2.5V＜Vin＜2.7V" condition?
Customer useing input voltage range is 2.7V～5V.
(It is 5 V of USB and battery voltage.)
However, when the output current is large,
The input voltage may be dropped (2.5V＜Vin＜2.7V) in some cases.

Let the following questions from the above background.

1.Is it a problem to use TPS61088 with "2.5V＜Vin＜2.7V" condition?
2.In the case of "2.5V＜Vin＜2.7V" condition, can you compensate the electrical characteristics?
　If it can not be guaranteed,Can you tell me the items that can not be guaranteed?

Best Regards,
Yusuke/Japan Disty

Hi sir,

After is the TPS61088 startup successfully at Vin>2.7V, it can work normally at 2.5-2.7V range. be sure the the Vin never drop below 2.5V at large load condition. or will trigger UVP.
