●General Description
■The TP7811 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 INon battery supply .the output voltage can be 12V drive OLED. A 2 ohm resistance of NMOS is integrated in the circuit, withstand voltage can support 22V, with a small SOT-23-5 package saves PCB space and BOM cost.
