A8501
OLED DRIVER
PWM CONTROL STEP-UP DC-DC CONVERTER
DESCRIPTION
FEATURES
The A8501 Series is a fixed frequency, constant
current step-up DC/DC converter ideal for driving
OLED. Output voltage of up to 22V can be derived,
and from a li-ion battery supply, the output voltage
can be 12V drive OLED. A 2Ω resistance of large
pipes is integrated in the circuit , withstand voltage
can support 22V, with a small SOT-25 package
saves PCB space and BOM cost.
The A8501 is available in SOT-25 package.
Input voltage range 2.7V~5.5V
Output voltage range up to 22V
Oscillation frequency 1MHz±20%
Efficiency 88%
Control PWM control
Stand-by Current ISTB=1.0uA(MAX)
Load capacitor 10uF,ceramic
LX limit Current 300mA
Available in SOT-25 Package
