LM2795 - Current Regulated Switched Capacitor LED Supply

This page provides the datasheet information for the LM2795, a member of the LM2794 Current Regulated Switched Capacitor LED Supply family.

Description

The LM2794/95 is a fractional CMOS charge-pump that provides four regulated current sources.

It accepts an input voltage range from 2.7V to 5.5V and maintains a constant current determined by an external sense resistor.

The LM2794/5 delivers up to 80mA of load current to accommodate four White LEDs.
