DESCRIPTION
   The EUP2520 is a dual step-up DC/DC converter, uses a single inductor and a schottky diode to provide two outputs. One is designed to drive up to 5 white LEDs with a constant current and the other is to power an organic LED display with a constant voltage. Each output is enabled by individual logic inputs.
