Descriptions
SC6022 is a highly integrated switching mode power
management IC (PMIC) designed to drive AMOLED
displays requiring ELVDD, ELVSS, AVDD, DVDD and VGL.
It can support up to 1.xA panel current with high panel
voltage to cover high brightness mode (HBM) applications.
The device integrates five high-performance converters,
Buck or Boost converter for ELVDD, inverting Buck-Boost
converters for ELVSS and VGL, Boost converter for AVDD
and Buck converter for DVDD. The ELVDD output has two
ranges. The first range is from 2.0V to 4.0V (default 2.8V) to
drive the LTPO panels. The second range is from 4.6V to
5.0V (default 4.6V) to drive LTPS panels. The ELVSS
inverting Buck-Boost adopts dual-phase topology and
supports up to -9V output voltage to provide continuous
high-power output and cover HBM panels. The AVDD,
DVDD and VGL are high-efficiency power solutions for
powering display driver IC.
The device is suited for lithium batteries with the best
performance from 2.8V to 5.0V. It uses innovative
technology enabling excellent output voltage regulation and
line transient performance. The output voltage is high
precision and programs through I2C.
For portable device applications, size, power consumption
and reliability are always the first consideration. SC6022
uses a tiny package and switches at 1.35MHz (Typ.) to
balance efficiency, inductors', and capacitors' size. Besides,
it also adopts synchronous rectification and power save
mode to maximum efficiency. The device integrates full
protections, including output short circuit protection,
overload protection, thermal shutdown, and input undervoltage
protection.
The SC6022 adopts 2.816mm × 2.976mm WLCSP package.
