Description
PM6680A is a dual step-down controller
specifically designed to provide extremely high
efficiency conversion, with loss less current
sensing technique. The constant on-time
architecture assures fast load transient response
and the embedded voltage feed-forward provides
nearly constant switching frequency operation. An
embedded integrator control loop compensates
the DC voltage error due to the output ripple.
Pulse skipping technique increases efficiency at
very light load. Moreover a minimum switching
frequency of 33 kHz is selectable to avoid audio
noise issues. The PM6680A provides a selectable
switching frequency, allowing three different
values of switching frequencies for the two
switching sections. The output voltages OUT1
and OUT2 can be adjusted from 0.9 V to 5 V and
from 0.9 V to 3.3 V respectively.
