High-Efficiency LCD Boost
with True Shutdown
General Description
The MAX8570 family of LCD step-up converters uses
an internal n-channel switch and an internal p-channel
output isolation switch. These converters operate from
a 2.7V to 5.5V supply voltage and deliver up to 28V at
the output.
A unique control scheme provides the highest efficien-
cy over a wide range of load conditions. The internal

MOSFET switch reduces external component count and
a high switching frequency (up to 800kHz) allows for
tiny surface-mount components. Three current-limit
options are available. The MAX8570 and MAX8572 use
a 110mA current limit to reduce ripple and component
size in low-current applications. For high-power require-

ments, the MAX8574 and MAX8575 use a 500mA cur-
rent limit and supply up to 20mA at 20V. The MAX8571
and MAX8573 use a 250mA current limit for a compro-
mise between ripple and power. Built-in safety features
protect the internal switch and down-stream compo-
nents from fault conditions.
Additional features include a low quiescent current and
a True Shutdown ? mode to save power. The MAX8570/
MAX8571/MAX8574 allow the user to set the output
voltage between 3V and 28V, and the MAX8572/
MAX8573/MAX8575 have a preset 15V output. These

step-up converters are ideal for small LCD panels with
low current requirements, but can also be used in other
applications. The MAX8571 evaluation kit is available to
help reduce design time.
