General Description

The LN2119 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 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.
