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 NMOS

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 600mA

 Available in SOT-25 Package

TYPICAL APPLICATION

VOUT = R1+ R2

VFB

R2

Note: R1 and R2 can be adjusted by the voltage of

VOUT and FB Pin; (when VOUT is equal to 12V,

recommended resistor R1 =875k, R2 =100k,

CP=100pF)
