Table 4-1 Jumpers and Switches
NO.FUNCTIONPLACEMENTCOMMENT
JP1Buck Enable (EN)Connect EN1 to GND to disable VOUT1, connect EN1 to VIN through a resistor to enable VOUT1; Leave open to enable VOUT1.
JP2Soft Start (SS)Connect a external cap to this pin to program the soft start time of the buck converter; leave this pin open to have default 1-ms soft start time.
JP3, 4Switching FrequencyConnect a resistor to this pin to set the switching frequency; leave it open to set FSW to 600 kHz; connect it to ground to set FSW to 300 kHz.
JP5Switch 2 EnableConnect this pin to high enable power switch 2; connect it to ground to disable power switch 2; Leave it open to enable power switch through internal 1.25-MΩ pull up resistor.Not recommend to leave open
JP6Switch 1 EnableConnect this pin to high enable power switch 1; connect it to ground to disable power switch 1; Leave it open to enable power switch through internal 1.25-MΩ pull up resistor.Not recommend to leave open
JP7PGOOD Pull UpConnect this pin to V7V force the PGOOD pull up. Connect this pin to GND there's no need to use this feature.Not recommend to leave open
