DESIGN IDEAS Multi-Output Supply Drives White
LEDs, Provides LCD or OLED Bias
in a 3mm Г— 3mm DFN Package
by Gurjit Thandi Introduction
Many of todayвЂ™s cell phones, PDAs
and digital still cameras contain a
high-resolution TFT-LCD display and
sometimes an additional secondary
OLED (Organic Light-Emitting Diode)
display. OLED displays are fast becoming the secondary display of choice
because they are brighter, thinner
and more responsive than equivalent
LCDs. The LT3466-1 is a dual switching regulator designed to meet the
power supply requirements of small
displays, including LCD-bias, white
LED backlight and OLED displays.
The LT3466-1 integrates a full
featured white LED driver and a boost
converter in a low proп¬Ѓle 3mm Г— 3mm
DFN package. It provides space and
component savings with integrated
44V power switches and Schottky
diodes. The LED driver can be conп¬Ѓgured to drive up to 10 white LEDs …
