Triple-Output AMOLED Display Power Supply Integrated Circuit IC
Chip
The SGM3836A is designed for powering AMOLEDdisplays which require
VAVDD, VELVDD and VELVSS. Thedevice integrates two boost
converters, VO1 for VELVDDand VO3 for VAVDD, and an inverting
buck-boostconverter VO2 for VELVSS. Output voltages of all thethree
converters can be programmed in digital stepsthrough the digital
interface control pin (CTRL).The SGM3836A is available in a Green
TQFN-3×3-16Lpackage. It operates over an ambient temperaturerange
of -40℃ to +85℃.
