PT4102 Datasheet (Micro Bridge Technology)

PT4102, Step-up White LED Driver

The PT4102 is a step-up DC/DC converter designed for driving up to 8 white LEDs in series from a single cell Lithium Ion battery with constant current.

Because it directly regulates output current, the PT4102 is ideal for driving light emitting diodes (LEDs) whose light intensity is proportional to
