Power Management
To optimize efficiency, the power management section of
the LTC3206 provides two methods of supplying power to
the CPO pin: 1x direct connect mode or 1.5x boost mode.
When any display of the LTC3206 is enabled, the power
management system connects the CPO pin directly to V
IN
with a low impedance switch. If the voltage supplied at V
IN
is high enough to power all of the LEDs with the pro-
grammed current, the system will remain in this “direct
connect” mode providing maximum efficiency. Internal
circuits monitor all current sources for the onset of “drop-
out,” the point at which the current sources can no longer
supply programmed current. As the battery voltage falls,
the LED with the largest forward voltage will reach the drop-
out threshold first. When any of the LED pins reach the drop-
out threshold, the LTC3206 will switch to boost mode and
automatically soft-start the 1.5x boost charge pump. The
constant frequency charge pump is designed to minimize
the amount of noise generated at the V
IN
supply.
