PT4110 Datasheet (Powtech) - High Efficiency White LED Driver

PT4110, High Efficiency White LED Driver

The PT4110 is a high efficiency step-up DC/DC converter designed for driving multiple strings of up to eight series-connected white LED from a single cell Lithium Ion battery.

It regulates the output current, ideal for driving light emitting diodes (LED) whose light intensity is proportional to the
