Table 5-2. Jumper Configurations

Controls EN1 and enables, disables VOUT1
Controls EN1 and enables, disables VOUT2
Sets DIA_EN and enables, disables diagnostics
Controls the SEL pin to set which diagnostics are reported by the SNS pin
Sets the functionality of the device during fault conditions via the LATCH pin
Enables, disables the on-board 3.3-V LDO. Must be set to top position (marked on silk screen as 3.3-V
LDO) to allow J8 to J12 to be high.
Controls which resistance value that is going into ILIM1. Only populate either J14 or J15 (not both) at a
time. If J14 is populated a 10-kΩ value is used and if J15 is used a 4.99-kΩ value is used for ILIM1. If
controlling from a from a microcontroller do not populate J14 or J15.
Controls whether or not to use the diode/resistor ground network for reverse current blocking. Populate
jumper to bypass ground network.
Selects if Vdd is being supplied by the BoosterPack or the on-board LDO. Do no populate if being supplied
externally through J6.
Controls if the FAULT line is being pulled up by the BoosterPack or the on-board LDO
Connects the BoosterPack 3.3-V rail to the on-board LDO's 3.3-V output giving the ability to power the
connected LaunchPad from the LDO.
Configures pin 18 to be connected to ILIMD in A, B, C version or FLT1 in D version
