  60V, 4-Switch Synchronous Buck-Boost Controller Regulates
  Voltage from Wide Ranging Inputs and Charges Batteries at
  98.5% Efficiency at 100W+
  Keith Szolusha The LTВ®3791-1 is a 4-switch synchronous buck-boost DC/DC converter that regulates
  both constant voltage and constant current at up to 98.5% efficiency using only a
  single inductor. It can deliver well over a hundred watts and features a 60V input
  and output rating, making it an ideal DC/DC voltage regulator and battery charger
  when both step-up and step-down conversion is needed. In addition to the high
  voltage, power and efficiency, it features short-circuit protection, a SYNC pin for
  synchronization to an external clock, a CLKOUT pin for driving an external SYNC
  pin or for parallel operation, OVLO (overvoltage lockout), SHORT output flag, C/10
  detection and output flag for battery chargers, and a CCM pin for discontinuous or
  continuous conduction mode. The inclusion of DCM (discontinuous conduction mode)
  increases light load efficiency and prevents reverse current when it is undesirable.

  VOLTAGE REGULATOR operates from an input voltage range
  of 12V to 58V. Adjustable undervoltage and overvoltage lockout protect
  the circuit. It has short-circuit protection and the SHORT output flag indicates The buck-boost converter shown in
