LM5150-Q1: 5150 under heavy load (2.5A), whether VIN=1.5V can work normally.

Part Number: LM5150-Q1

Hi team,

The customer used LM5150-Q1 for BUB in TBOX. The specifications are as follows:

VIN=1.5V-4.5V,OUTPUT6.8V,Ipeak 2.5A 5ms.Attached is the schematic diagram.

Customers have questions about whether the input voltage can be reduced to 1.5V due to the internal resistance of the battery when the input voltage is reduced to 1.5V after normal operation?
Although the Datasheet explains that 1.5V can work, does this specification take into account the loss of voltage or the loss of diodes, etc.?
