What is ZETA DC/DC Converter for LED Driving about?

This document describes a proposed LED lamp driver using a ZETA DC/DC converter to improve LED drive characteristics and achieve greater durability and efficiency. The ZETA converter provides constant current to the LED lamp using average current mode control. Experimental results on a prototype show the converter maintains output current as input voltage varies, ensuring high luminous efficiency of around 272 lumens/watt for the LED lamp. The ZETA converter and constant current drive provide long life and
