G2621 - Constant Current 40V White-LEDs Driver

Download the G2621 datasheet PDF. This datasheet also covers the G2621-GlobalMixed variant, as both devices belong to the same constant current 40v white-leds driver family and are provided as variant models within a single manufacturer datasheet.

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.

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.
