General Description

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 current passing through them.

The external ballast resistor sets the LED current ranging from 5mA to 20mA, which can be easily adjusted using either a DC voltage or a pulse width modulated (PWM) signal alternatively.

Key Features

to protect itself from fault conditions including built-in open load protection, cycle-by-cycle current limit, over temperature shutdown, input under voltage control and integrated soft-start. The PT4110 is available in SOT-89-5 and SOP-8 packages.
