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 -40℃ to +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.
