OPERATIOU
Main Control Loop
The LTC3776 uses a constant frequency, current mode
architecture with the two controllers operating 180 de-
grees out of phase. During normal operation, the top
external P-channel power MOSFET is turned on when the
clock for that channel sets the RS latch, and turned off
when the current comparator (I
CMP
) resets the latch. The

OVP
peak inductor current at which I
CMP
resets the RS latch is
determined by the voltage on the I
TH
pin, which is driven
by the output of the error amplifier (EAMP). The V
FB
pin
receives the output voltage feedback signal from an exter-
nal resistor divider. This feedback signal is compared to a
reference (either the internal 0.6V reference for controller
1 or the divided down V
REF
pin for CH2) by the EAMP.
