TPS51601A: DC-DC synchronous boost circuit the boost driver TPS51601A no output

Part Number: TPS51601A
Other Parts Discussed in Thread: CSD17308Q3, TPS51604

Hello Sr,

I am currently using your synchronous boost chip TPS51601A drives both high-side and low-side FETs(CDS17308Q3),there is no signals output on DRVH and DRVL when input 200Khz pulse on PWM pin,none-of pulls up or pulls down on  /SKIP pin,and the supply voltage on VDD is 6Vdc. could you pls provide support to find what's going on. any tips you could provide on how to use this chip is very appreciated!
