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 resistordivider. 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.
