LT3758 36V to 72V Input, 3.3V Output Isolated Telecom Power Supply

36V to 72V Input, 3.3V Output Isolated Telecom Power Supply

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. The LT3758/LT3758A drive a low side external N-channel power MOSFET from an internal regulated 7.2V supply. The fixed frequency, current-mode architecture results in stable operation over a wide range of supply and output voltages.
