LT8708-1
80V Synchronous 4-Switch Buck-Boost DC/DC
Slave Controller for LT8708 Multiphase System
FEATURES DESCRIPTION Slave Chip of LT8708 to Deliver Additional Power
nn Good Current Matching to the Average Output
Current of LT8708 Through Current Regulation
nn Easily Paralleled with LT8708 Through Four Pins
nn Synchronized Start-Up with LT8708
nn Same Conduction Modes as LT8708
nn Synchronous Rectification: Up to 98% Efficiency
nn Frequency Range: 100kHz to 400kHz
nn Available in 40-Lead (5mm × 8mm) QFN with High
Voltage Pin Spacing The LT®8708-1 is a high performance buck-boost
switching regulator controller that is paralleled with the
LT8708 to add power and phases to an LT8708 system.
The LT8708-1 always operates as a slave to the master
LT8708 and has the capability of delivering as much current or power as the master. One or more slaves can be
connected to a single master, proportionally increasing
power and current capability of the system. nn APPLICATIONS
High Voltage Buck-Boost Converters
Bidirectional Charging Systems
nn Automotive 48V Systems
nn The LT8708-1 has the same conduction modes as LT8708, …
