TPS62088: leakeage when Vin lower than Vuvlo

Martin Andersson70

Part Number: TPS62088

When Vin is lower than Vuvlo we see a leakage to gnd, the leakage is in the range of mA and increase with temperature. We are not using the device but it is an issue that it consumes power since it drains the battery.Is this a known issue?

Hi Martin,

The shutdown current is known to be around 200uA for Vin< UVLO, so what you see is a bit unusual.
What's the resolution of the instrument you are using for measuring this value?
