LT8705EUHF#TRPBF

LT8705 is a high performance buck-boost switching regulator controller that 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. This device 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, on-board gate drivers, adjustable UVLO, along with input and output current monitoring with programmable maximum levels. It is widely used in application such as high voltage buck-boost converters, input or output current limited converters etc.
