LCD AND OLED BIAS BOOST CONVERTER - STN, CSTN SCREENS
DESCRIPTION
The ZXLB1600 inductive switching boost converter
accepts an input voltage of between 1.6V and 5.5V and
provides an adjustable output voltage of up to 28V for
FEATURES
? Wide input voltage range: 1.6 to 5.5V
? Adjustable output voltage up to 28V, using PWM
or analog control voltage
LCD and OLED bias. The device contains an output
switch and a second switch to isolate the coil from the
input to provide true isolation in shutdown mode. The
output can be adjusted by means of an externally
applied dc voltage, a PWM control signal, or external
feedback resistors and can supply typically 10mA of
output current at maximum output voltage. Higher
current is available at lower output voltages.
The input voltage range accepts a number of battery
solutions, including dual dry cell and single Li-Ion cells
and PFM operation mode allows the output to be
regulated with high efficiency under light or no load
conditions. The switching frequency range permits the

Internal PWM filter
True shutdown (output isolated from input)
Internal output switch and current sense
Low quiescent current: (75 A max)
5 A (max) shutdown current (including low
battery comparator)
Up to 500kHz switching frequency
High efficiency
Small MSOP10 package
Low external component count
use of miniature surface mount inductors.
APPLICATIONS
A low battery comparator is provided to indicate when
the input voltage has fallen to within ± 2% of a preset
threshold. This threshold is set internally , but can be
adjusted externally to any voltage within the supply
voltage range.
