LTC3780
High Efficiency, Synchronous,
4-Switch Buck-Boost Controller
DESCRIPTIO
The LTC
廬
3780 is a high performance buck-boost switch-
ing regulator controller that operates from input voltages
above, below or equal to the output voltage. The constant
frequency current mode architecture allows a phase-
lockable frequency of up to 400kHz. With a wide 4V to 30V
(36V maximum) input and output range and seamless
transfers between operating modes, the LTC3780 is ideal
for automotive, telecom and battery-powered systems.
The operating mode of the controller is determined through
the FCB pin. For boost operation, the FCB mode pin can
select among Burst Mode
廬
operation, Discontinuous mode
and Forced Continuous mode. During buck operation, the
FCB mode pin can select among Skip-Cycle mode, Discon-
tinuous mode and Forced Continuous mode. Burst Mode
operation and Skip-Cycle mode provide high efficiency
operation at light loads while Forced Continuous mode
and Discontinuous mode operate at a constant frequency.
Fault protection is provided by an output overvoltage
comparator and internal foldback current limiting. A Power
Good output pin indicates when the output is within 7.5%
of its designed set point.
