Note 1.
Note 2.
Note 3.
Note 4.
Note 5.
All parameters are tested at T A =25°C, unless otherwise noted. Specifications at temperature are guaranteed by design
Subject to thermal dissipation characteristics of the device
When mounted according to JEDEC JEP149 and JESD51-12 for a two-layer PCB, θ JA = 24.1°C/W and θ JC = 2.7°C/W
Guaranteed by design and characterization. Not production tested
STR0 to STR5 current matching is the difference between any one string current and the average of all string currents divided
by the average of all string currents
Note 6. The MSL1060 selects the active string (STR0 through STR5) with the lowest voltage to control the boost regulator voltage
