MAX8678ETE+T

LED Driver IC Overview

The MAX8678ETE+T is a single-wire dimmable LED driver IC manufactured by Analog Devices Inc./Maxim Integrated. It integrates a switched-capacitor (charge pump) DC-DC regulator with four independent output channels, each capable of delivering up to 24mA. The device operates within a supply voltage range of 2.7V to 5.5V and supports individual channel enable control. It is housed in a compact 16-pin TQFN package measuring 3mm x 3mm. The component is designed for efficient LED illumination control in portable applications.
