Wide Input Voltage Range Boost/Inverting/SEPIC Controller
Works Down to an Input Voltage of 1.6V
Design Note 500
Zhongming Ye
Introduction
Many of todayвЂ™s electronic devices require 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 LTВ®3759 operates over an input voltage range from
1.6V to 42V and controls either positive or negative
outputs using the same feedback pin, thus shortening
the inventory list and simplifying design. It also packs
many popular features such as soft-start, adjustable
frequency and synchronization into a small footprint.
The LT3759 comes in a 5mm Г— 4mm 12-pin MSE package and can be used in multiple configurations such as
boost, SEPIC, flyback and Cuk topologies.
