TPS61021A: Startup problem with a load is connected

Part Number:TPS61021A

Hello,

I am testing a design with the TPS61021A.

Input voltage is 0.9V to 1.8V

Output voltage is 2.2V

Output current is 100 mA 

I have a design pretty similar to the webench attached. I have more capacitor on the input.

Inductor is the datasheet recommended from Coilcraft.


When I apply the power between 0.9V to 1.8V, with my small load connected (Resistor for 100mA current), the output voltage stays at around 0.7 V.

If I remove the load, the output goes at 2.2V.


What could be the problem ?  What needs to be checked first ?

Could it be the enable attached directly to Vin ?

Thanks !
