The LT8705EFE#PBF is a 80V synchronous 4-switch Buck Boost DC/DC Controller operates from input voltages above, below or equal to the output voltage. The part has integrated input current, input voltage, output current and output voltage feedback loops. With a wide 2.8 to 80V input and 1.3 to 80V output range, the LT8705 is compatible with most solar, automotive, telecom and battery-powered systems. The LT8705 includes servo pins to indicate which feedback loops are active. The MODE pin selects among Burst Mode?? operation, discontinuous or continuous conduction mode at light loads. Additional features include a 3.3V/12mA LDO, a synchronizable fixed operating frequency, onboard gate drivers, adjustable UVLO, along with input and output current monitoring with programmable maximum levels.
