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.



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 I_STB=1.0uA(MAX)

Load capacitor 10uF,ceramic

LX limit Current 600mA

Available in SOT-25 Package

The A8501 is available in SOT-25 package.
