Introduction
As portable devices become more sophisticated and
require higher display resolution, there is an increased
demand for accurate, high voltage bias supply solutions with wide input and output voltage ranges. The
traditional methods of using arrays of capacitors to
implement a charge pump or a bulky and expensive
transformer no longer meet the accuracy and size
requirements of todayвЂ™s portable devices.
The LTВ®3463 is both accurate and compact. It п¬Ѓts both
a positive output converter plus a negative output converter into a tiny (3mm Г— 3mm)DFN package, including Schottky diodes and switches capable of 250mA
(400mA on the negative channel of the LT3463A).
The LT3463 works in a wide range of applications due to
its 2.3V to 15V input voltage range and output capability
to В±40V. Each converter is designed to operate with a
quiescent current of only 20ОјA, which drops to less than
1ОјA in shutdown, making the LT3463 solution ideal for
battery-powered portable applications.
