DESIGN FEATURES Triple Output LCD Power Supply
Delivers 95% Efficiency from a
Tiny 3mm x 3mm Package by John Bazinet
Introduction
TodayвЂ™s handheld products pack more
functionality in less space while demanding improved battery life over
products of the previous generations.
The only way to achieve both is to improve power efficiency in the device
wherever possible. The color LCD display system is a good place to start,
since it is an increasingly popular, but
power hungry feature. The LTC3450
improves battery life and saves space
by delivering a 95% efficient color LCD
bias solution in a low profile (0.8mm
tall), 3mm Г— 3mm package.
Figure 1 shows a block diagram of
the LTC3450вЂ”a complete triple output
LCD power converterвЂ”in a low noise
5.1V, 10mA output synchronous step
up DC/DC converter. The charge pump based voltage tripler develops a 15V
output and a voltage inverter develops
вЂ“10V. The 15V and вЂ“10V outputs are
used in the LCD display for VGL and …
