Nowadays many of electronic devices call for an inverting or noninverting converter or sometimes both. They also need to operate from a variety of power sources including USB, wall adapters, alkaline and lithium batteries. To produce various polarity outputs from variable input voltages, power supply designers often use a variety of regulator ICs, which makes for a long inventory list.

The LT3759 operates over an input voltage range from 1.6V to 42V and controls either positive or negative outputs using the same feedback pin, thus it is touted to shorten the inventory list and simplify design. It also has features such as soft-start, adjustable frequency and synchronisation. The LT3759 comes in a 5mm 4mm 12-pin MSE package and can be used in multiple configurations such as boost, SEPIC, flyback and Cuk topologies.
