LT3791EFE-1#PBF General Description

The LT3791-1 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 to 700kHz. No top FET refresh switching cycle is needed in buck or boost operation. With 60V input, 60V output capability and seamless transitions between operating regions, the LT3791-1 is ideal for voltage regulator, battery/super-capacitor charger applications in automotive, industrial, telecom, and even battery-powered systems.

For new designs we recommend the LT8390: 60V synchronous 4-switch buck-boost controller due to its numerous performance improvements over the LT3791-1.
