LT8705 Datasheet Synchronous 4-Switch Buck-Boost DC/DC Controller

Manufacturer: Linear Technology (now Analog Devices)

Overview: LT8705 80V VIN and VOUT Synchronous 4-Switch BuckBoost DC/DC.

General Description

The LT®8705 is a high performance buck-boost switching regulator controller that operates from input voltages above, below or equal to the output voltage.

The part has integrated input current, input voltage, output current and output voltage feedback loops.

With a wide 2.8V to 80V input and 1.3V to 80V output range, the LT8705 is compatible with most solar, automotive, telecom and battery-powered systems.
