DESCRIPTION
The LT®3791-1 is a synchronous 4-switch buck-boost voltage/current regulator controller. The controller can regulate output voltage, output current, or input current with input voltages above, below, or equal to the output voltage.
   
FEATURES
■ 4-Switch Single Inductor Architecture Allows VIN
