MAX8630ZETD25+T

LED Driver IC Overview

The MAX8630ZETD25+T is a single-chip LED driver designed for powering five white LEDs. It utilizes a switched-capacitor charge pump topology to efficiently regulate current from a single-cell lithium-ion battery or similar input source. The device operates at a switching frequency of 1MHz and provides multi-step dimming control. It features an internal switch configuration and delivers a channel output current of 25mA per LED. Packaged in a compact 14-TDFN-EP (3x3 mm) surface-mount package with an exposed pad, it supports an operating temperature range of -40°C to +85°C.
