MAX8630XETD20+T

LED Driver IC Overview

The MAX8630XETD20+T is a multi-output LED driver IC from Analog Devices/Maxim Integrated, designed for driving white LEDs. It utilizes a switched capacitor (charge pump) architecture to provide five non-isolated outputs with a typical output current of 25mA per channel. The device operates within an input voltage range of 2.7V to 5.5V and features a switching frequency of approximately 1MHz. It is housed in a compact 14-TDFN (3x3mm) package with an exposed pad, suitable for space-constrained portable applications.
