MAX17010
Internal-Switch Boost Regulator with Integrated High-Voltage Level Shifter and Op Amp
LCD display bias IC with integrated scan driver offers new level of integration and functionality
|
Status
Active: In Production.
Description
The MAX17010 contains a high-performance step-up
switching regulator, a high-speed operational amplifier
(op amp), and a high-voltage level-shifting scan driver.
The device is optimized for thin-film transistor (TFT) liquid-crystal
display (LCD) applications.
The step-up DC-DC converter provides the regulated
supply voltage for the panel-source driver ICs. The converter
is a 1.2MHz current-mode regulator with an integrated
20V n-channel power MOSFET. The high
switching frequency allows the use of ultra-small inductors
and ceramic capacitors. The current-mode control
architecture provides fast transient response to pulsed
loads. The step-up regulator features undervoltage
lockout (UVLO), soft-start, and internal current limit. The
high-current op amp is designed to drive the LCD
backplane (VCOM). The amplifier features high output
current (±150mA), fast slew rate (45V/µs), wide bandwidth
(20MHz), and rail-to-rail inputs and outputs.
The high-voltage, level-shifting scan driver is designed
to work with panels that incorporate row drivers on the
panel glass. Its eight outputs swing from +30V (max) to
-10V and can swiftly drive capacitive loads.
The MAX17010 is available in a 40-pin thin QFN package
with a maximum thickness of 0.8mm for ultra-thin
LCD panels. The device operates over the -40°C to
+85°C temperature range.
