Drive Large TFT-LCD Displays with a Space-Saving Triple-Output
Regulator вЂ“ Design Note 417
Jesus Rosales Introduction
The power appetite of large TFT-LCDs appears to be
insatiable. Power supplies must feed increasing numbers
of transistors and improved display resolutions, and do
so without taking much space.
The triple output supply shown in Figure 1 shows a compact design based on the LT3489, which is optimized for
driving large TFT panel displays. The main output provides
8V at 600mA while the 23V and вЂ“8V outputs provide 10mA
and 20mA respectively, all from a 3.3V input. Even though
TFT converters generally run from a regulated 3.3V or
5V source, this converter can operate seamlessly from
a Lithium-Ion battery, delivering 5W when the battery is
drained to 3.3V and 8W when it is at 4.2V.
The LT3489 squeezes a 2.5A, 0.12О©, 40V switch into a
tiny 3mm Г— 3mm MS8E footprint. It offers external or
internal compensation, an internal soft-start, a 2MHz switching frequency, and it is also pin compatible with
the popular LT1946. The design process with the LT3489
is easy and predictable.
The circuit in Figure 2 operates as a SEPIC converter,
allowing the output to be higher or lower than the input.
Pulling the вЋЇSвЋЇHвЋЇDвЋЇN pin to ground sets the output at 0V even …
