Product Overview

The LT3791EFE-1#PBF is a 60V 4-switch Synchronous Buck-Boost Controller regulates 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 200 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. It provides input current monitor, output current monitor and various status flags, such as C/10 charge termination and shorted output flag.
  • 4-switch single inductor architecture allows VIN above, below or equal to VOUT
  • Up to 98.5% efficiency synchronous switching
  • Wide VIN range (4.7 to 60V)
  • 2% Output voltage accuracy (1.2V <= VOUT < 60V)
  • 6% Output current accuracy (0V <= VOUT < 60V)
  • Input and output current regulation with current monitor outputs
  • No top FET refresh in buck or boost
  • VOUT disconnected from VIN during shutdown
  • C/10 charge termination and output shorted flags
  • Capable of 100W or greater per IC
