SGM3852 Datasheet Pmic

Manufacturer: SG Micro

Overview: SGM3852 PMIC for LTPO and Tandem AMOLED Display GENERAL.

General Description

The SGM3852 is designed for powering LTPO (Low Temperature Polycrystalline Oxide) and Tandem structure AMOLED displays which require VELVDD, VELVSS, VAVDD, VDVDD and VVGL.

The device integrates two Buck converters VO1 for VELVDD and VO4 for VDVDD, one Boost converter VO3 for VAVDD, one dual-phase inverting Buck-Boost converter VO2 for VELVSS and one single-phase inverting Buck-Boost converter VO5 for VVGL.

Output voltages of all the five converters can be programmed in digital steps through the I2C interface.

Key Features
