Multi-Output DC-DC Power Supply with

VCOM Amplifier and Temperature Sensor for

E-Paper Applications

General Description

Features

S Four Regulated Output Voltages for Source- and

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.

S Measures Internal and Re0ote Diode ꢀe0perature

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

) is always tightly regulated to -V

within Q50mV.

POS

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.

Simplified Operating Circuit

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

2.7V TO 5.5V

INPUT

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
