General Description

The SGM3851A is designed for powering AMOLED displays which require VAVDD, VELVDD and VELVSS.

The device integrates two boost converters, VO1 for VELVDD and VO3 for VAVDD, and an 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 (CTRL).

Key Features

  • 2.9V to 4.5V Input Voltage Range.
  • Synchronous Boost Converter (ELVDD).
  • 4.6V to 5.0V Output Voltage with 100mV Steps.
  • 4.6V Default Output Voltage.
  • 1.2% Accuracy.
  • 400mA Output Current Capability.
  • Output Voltage Sensing Pin for Path Loss Compensation (FBS).
  • Synchronous Inverting Buck-Boost Converter (ELVSS).
  • -5.4V to -1.4V Output Voltage with 100mV Steps.
  • -2.5V Default Output Voltage.
  • 1.6% Accuracy at -2.5V (±40mV).
  • 400mA Output Current.
