Page 5: Current Adjustment
Boost to ground evaluation kit TLD5099EP B2G 3 Current adjustment Current adjustment Output current adjustment can be performed by changing the value of trimmer R15 with a screwdriver, when X10 is closed in position 1-2 and X12 is closed. Output current can vary from 0 to 100% of the maximum output current (in this evaluation board from 0 to 350 mA). -
Page 6: Power Derating (Battery Dependent Current)
Boost to ground evaluation kit TLD5099EP B2G 4 Power derating (Battery dependent current) Power derating (Battery dependent current) Power derating acts by reducing V (and thus the output current) when the battery voltage drops below 8 V. It works better when R15 is trimmed to its maximum value, otherwise a different derating profile is applied. If a different derating profile is needed, R14 has to be changed accordingly, in order to have 1.6 V on pin SET when... -
