BoosterPack XL Interface on the J3 01 pin This is a direct connection with only small decoupling capacitors provided on the Stellaris LaunchPad All LaunchPads including the Stellaris LaunchPad also provide a 3 3 V supply on pin J1 01 of the BoosterPack interface On the Stellaris LaunchPad this is sourced by a TPS73633 LDO voltage regulator which converts the selected 5 V USB power to 3 3 V The regulator is capable of sourcing 400 milliamps at 3 3 V This 3 3 V supply is shared between the BoosterPack interface the in circuit debug interface ICDI and the target microcontroller Therefore under normal circumstances about 300 to 350 milliamps are available to the BoosterPack interface Detailed power management is left to the BoosterPack developer who must also manage the application to be run on the target microcontroller The Stellaris LaunchPad can be powered through an external supply on a BoosterPack If providing power to the Stellaris LaunchPad from a BoosterPack move the power select switch to select an unused USB connection to prevent power bus contention between the BoosterPack and the USB connection Power may be supplied to either the 3 3 V or the 5 0 V system but not both Providing external power to both 5 V and 3 3 V would result in a contention between the external power supplies and the Stellaris LaunchPad s voltage regulator Providing only 3 3 V will result in some lost functionality such as the on board LED s It may also r
