Triple-Output  
AMOLED Display Power Supply  
ELVDD & ELVSS Combined Output Current  
Capability  
GENERAL DESCRIPTION  
The SGM3836A 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).  
Up to 800mA at 4.6V/-2.5V (VIN = 3.1V)  
Up to 780mA at 4.6V/-2.7V (VIN = 3.1V)  
Up to 750mA at 4.6V/-3.0V (VIN = 3.1V)  
Up to 630mA at 4.6V/-4.0V (VIN = 3.1V)  
Up to 510mA at 4.6V/-5.4V (VIN = 3.1V)  
Synchronous Boost Converter (AVDD)  
5.8V to 7.9V Output Voltage with 300mV Steps  
6.1V Default Output Voltage  
The SGM3836A is available in a Green TQFN-3×3-16L  
package. It operates over an ambient temperature  
range of -40to +85.

ESD SENSITIVITY CAUTION  
This integrated circuit can be damaged if ESD protections are  
not considered carefully. SGMICRO recommends that all  
integrated circuits be handled with appropriate precautions.  
Failureto observe proper handlingand installation procedures  
can cause damage. ESD damage can range from subtle  
performance degradation tocomplete device failure. Precision  
integrated circuits may be more susceptible to damage  
because even small parametric changes could cause the  
device not to meet the published specifications.
