LT3757A - SEPIC and Inverting Controller
The LT®3757/LT3757A 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 LT3757/LT3757A drive a low side external N-channel power MOSFET
