LT3758A Datasheet Inverting Controller

Manufacturer: Linear Technology (now Analog Devices)

General 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.

The LT3758/LT3758A drive a low side external N-channel power MOSFET from an internal regulated 7.2V supply.
