我看了一下数据手册,PSI是决定供电输出相数的一个信号。0.9 是自动模式。数据手册上对PSI 的解释。
When PSI = High, the controller operates with all activephases enabled regardless of the load current. If PSI = Mid,the NCP81610 operates in dynamic phase shedding modewhere the voltage present at the IOUT pin (the total loadcurrent) is measured every 10 s and compared to thePHTHX thresholds to determine the appropriate powerzone
When PSI = low, the controller is set to a fixed power zoneregardless of the load current, programmable through userregister 0x34 and 0x36. The LPC2 setting controls the powerzone used during cold boot−up (After power on VCCUVLO, EN is set high) while the LPC1 configuration setsthe power zone in the consecutive soft startup by togglingEN only (soft boot−up).
还有很多。可以自己查看芯片数据手册。
