Introduction
The LTMВ®8055 is a buck-boost ВµModuleВ® regulator with
a 5V to 36V input range that can be easily paralleled to
extend load current capability. Its 4-switch buck-boost
topology features high efficiency while allowing the
input voltage to be below, at or above the outputвЂ”with
smooth transitions between regulation modes. The
LTM8055 can regulate a constant-voltage (CV) and a
constant-current (CC) output, with analog programming of output current. Its out-of-phase clock output,
combined with switching frequency synchronization, 0.22ВµF C5
