DESCRIPTION
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.
