TPS61089EVM-742: TPS61089 couldn't handle 2Amp load even the datasheet says it can.

Prodigy 20 points
Part Number: TPS61089EVM-742
Other Parts Discussed in Thread: TPS61089,

Hi,

I need to boost 3.3v (battery powered) to 9v to drive a DC solenoid. the solenoid requires minimum 1.6Amp. Hence I purchased TPS61089EVM-742 to test its capability because I saw TPS61089 can handle up to 2 Amp from the datasheet. I was able to get 9v from a 3.3v battery without any load. Once I connect the solenoid, the output voltage drop to 3.6v which couldn't meet the requirement of the solenoid. Why did the voltage drop even the datasheet says it can handle up to 2Amp? If this chip is no good for my purpose, please make a recommendation.

Thanks!
