n 38-Lead TSSOP with Exposed Pad 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. The
constant-frequency, current mode architecture allows its
frequency to be adjusted or synchronized from 200kHz …
