TPS61236P: strange noise and not enough power

Part Number: TPS61236P

Hi,

I'm using TPS61236P in order to convert the typical 2.9/4.1V of a li-ion battery to 5V but, after I designed the pcb circuit (all with >10mil traces), the converter output 5V but less than 200mA and the inductance is making some strange "ticking" noise. I attach the schematic and the board layout I designed based on WEBENCH parameters. Are the traces the problem?

Thank you so much,

Simone
