SGM3837

Triple-Output 600mA

AMOLED Display Power Supply

 -4.0V Default Output Voltage

 -600mA Output Current Capability

(V_ELVSS= -1.0V to -5.4V)

GENERAL DESCRIPTION

The SGM3837 is designed for powering AMOLED

(Active Matrix Organic LED) displays which require

● Synchronous Boost Converter (AVDD)

 7.1V to 7.8V Output Voltage (SET = Low)

V_ELVDD, V_ELVSSand V_AVDD. The device integrates two

Boost converters, VO1 for V_ELVDDand VO3 for V_AVDD

and one inverting Buck-Boost converter VO2 for V_ELVSS

Output voltages of all the three converters can be

programmed in digital steps through the digital interface

control pins (ASWIRE & ESWIRE).

 6.9V to 7.9V Output Voltage (SET = High)

 7.6V Default Output Voltage

 150mA Output Current Capability

● Selectable ASWIRE Setting via SET pin

● V_INand V_OUTBi-Directional Isolation

● Short Circuit Protection (SCP)

The SGM3837 is available in a Green WLCSP-2.0×

2.0-25B package.

● Overload Protection

● Thermal Shutdown

● V_ELVSSStart-Up Delay: 10.4ms

● Short Circuit and OLP Detection Time: 0.08ms

● Available in a Green WLCSP-2.0×2.0-25B Package

FEATURES

● 2.9V to 5.0V Input Supply Voltage Range

● Synchronous Boost Converter (ELVDD)

 4.6V to 5.0V Output Voltage with 100mV Steps

 4.6V Default Output Voltage

APPLICATIONS

Smartphone & Tablet

 600mA Output Current Capability

● Synchronous Inverting Buck-Boost Converter

(ELVSS)

Active Matrix OLED Display

 -6.6V to -1.0V Output Voltage with 100mV Steps
