Part Number: BQ24259

I am using BQ24259 IC. I have enabled Boost mode as per data sheet (Mentioned in Page No:16).I read back STATS REGISTER (0x08) and VBUS_STAT[1],VBUS_STAT[0] Both are high thus the OTG is enabled. But Still i am not getting Boosted Voltage out. In hardware i am also made OTG pin high for boost mode Please Help me to troubleshoot the same
