APPLICATIONS
n Automotive n Telecom n Industrial LT3758/LT3758A High Input Voltage, Boost, Flyback, SEPIC and Inverting Controller DESCRIPTION
The LT®3758/LT3758A are wide input range, current mode, DC/DC controllers which are capable of generating either positive or negative output voltages. They can be configured as either a boost, flyback, SEPIC or inverting converter. A minimum operating supply voltage of 5.5V, and a low shutdown quiescent current of less than 1µA, make the LT3758/LT3758A ideally suited for batterypowered systems.
