General Description

The SGM3838 is designed for powering AMOLED displays which require VELVDD, VELVSS and VAVDD.

The device integrates two Boost converters, VO1 for VELVDD and VO3 for VAVDD, and a dual-phase inverting Buck-Boost converter VO2 for VELVSS.

Output voltages of all the three converters can be programmed in digital steps through the digital interface control pin (SWIRE).

Key Features

  • 2.5V to 4.8V Input Supply Voltage Range.
  • Synchronous Boost Converter (ELVDD).
  • 4.6V to 5.0V Output Voltage with 100mV Steps.
  • 4.6V Default Output Voltage.
  • 0.7% Accuracy at 4.6V.
  • 700mA Output Current Capability.
  • Output Voltage Sensing Pin for Path Loss Compensation (FBS).
  • Synchronous Inverting Buck-Boost Converter (ELVSS).
  • -6.0V to -0.8V Output Voltage with 100mV Steps.
  • -3.0V Default Output Voltage.
  • 1% Accuracy at -3V.
  • 700mA Output Curre.
