General Description

The G2621 step-up converter drives white LEDs with a constant current to provide backlight in cell phones, PDAs, and other hand-held devices.

Overview

Global Mixed-mode Technology G2621 High Efficiency, Constant Current 40V White-LEDs Driver Feature Operating Voltage: 2.5V to 5.5V.

High Operating Frequency: 1MHz High Output Voltage: Up to 40V(Typ.) Digital Dimming Control.

Built-in Cycle-by Cycle Current-Limiting.

Key Features

allowing series connection of the white LEDs so that the LED currents are identical for uniform brightness. An enable input can be pulsed repeatedly to adjust LED’s brightness. The fast 1.0MHz current-mode PWM control allows for smaller capacitor and inductor. Fault condition protection uses cycle-by-cycle current limiting to sense maximum inductor current, thermal protection and over-voltage protection. Also included soft-start eliminates inrush current during start-up. The 0.2V low reference v.
