TPS61230: The input GND have res to GND

Part Number: TPS61230

Hi Team,

My customer now use TPS61230.

But the input from backup battery has a 3.8 ohm to GND.

But with the 3.8 ohm from Front circuit, TPS61230 circuit will oscillate; When customer disconnected Front circuit, which means no 3.8ohm.TPS61230 could work normally.

May I ask how could TPS61230 could work normally even with 3.8 ohm to GND?
