SGM3804 Datasheet Buck/boost Converter

Manufacturer: SG Micro

Overview: SGM3804 Single Inductor, Positive/Negative Dual Output, Buck/Boost Converter.

General Description

The SGM3804 generates both positive and negative precision regulated voltage power sources, with a patent pending control scheme for single inductor dual output converter.

Outputs are programmable in 100mV steps in 2.4V to 6.4V range, which are commonly used in drivers for LCD displays and AMOLED displays, as well as in any other circuits requiring both rails, with different loading on each rail.

The device is equipped with I2C interface.

Key Features

  • Single Inductor for Positive & Negative Outputs.
  • High Efficiency in Wide Output Loading Range.
  • Outputs Programmable with I2C Interface.
  • 2.4V to 6.4V Programmable for Both Outputs.
  • Factory Programmable Default Outputs: SGM3804-0: VPO = +5.4V/VNO = -5.4V SGM3804-1: VPO = +4.6V/VNO = -3.5V SGM3804-2: VPO = +5.0V/VNO = -5.0V SGM3804-3: VPO = +4.6V/VNO = -2.4V SGM3804-4: VPO = +6.4V/VNO = -6.4V.
  • 1.6MHz Switching plus Pulse-Skip Operation.
  • Configurable Stop Active D.
