TPS60230
SLVS516A – MAY 2004 – REVISED JUNE 2004
For example, the worst case power dissipation occurs at the input voltage level where the charge pump switches
from the 1x mode to the 1.5x mode. At this operating point, the supply voltage to the current sources is at its
maximum and the current sources must drop the most voltage in order to maintain a regulated output current.
The worst case power dissipation occurs when all 5 LED outputs are fully loaded with 25 mA of LED current.
With: VI = 4.2 V, Vf = 3.6 V, IO = 125 mA (1.5x mode)
PD max = 0.39 W
