Multi-Output DC-DC Power Supply with
VCOM Amplifier and Temperature Sensor for
E-Paper Applications
General Description
The MAX17135 is a complete power-management IC for
E-paper displays that provides source- and gate-driver
power supplies, a high-speed VCOM amplifier, and a
temperature sensor.
The source-driver power supplies consist of a boost
converter and an inverting buck-boost converter that
generates +15V (up to +17V) and -15V (up to -17V),
respectively. Both source-driver power supplies can
deliver up to 200mA. The positive source-driver supply
regulation voltage (VPOS) can be set either by using
an I2C interface or by connecting an external resistor-
divider. The negative source-driver supply voltage
(VNEG) is always tightly regulated to -VPOS within Q50mV.
The gate-driver power supplies consist of regulated
charge pumps that generate +22V (up to +40V) and
-20V (up to -40V) and can deliver up to 20mA each.
The IC features a VCOM amplifier output whose output
voltage is controlled by an internal 8-bit digital-to-analog
converter (DAC). The DAC is programmable through an
I2C interface and allows small-voltage-step sizes per
DAC step.
The IC includes a temperature sensor that provides
the ability to read the internal IC temperature and an
external panel temperature with the use of an external
temperature-sensing diode. Temperature output data is
supplied through I2C.
The device is available in a space-saving, 32-pin TQFN
package and is specified over the -40NC to +85NC
extended temperature range.

Power Ground
Feedback Pin for HVINP Output. Connect FBP to GND to set the HVINP regulation voltage to +15V. With
FBP connected to ground, VHVINP can be changed through I2C after power-up by changing the value
stored in the HVINP register. Alternatively, connect an external resistor-divider midpoint to the FBP pin to
set the HVINP regulation voltage.
Power Input. Bypass to GND through a minimum 1FF capacitor.
Exposed Pad. Connect exposed pad to ground.
