IS32FL3268 - 24-CHANNEL 16-BIT PWM LED DRIVER

Datasheet Summary

Description

The IS32FL3268 is a 24-channel constant current LED driver.

Each channel has 16-bit PWM brightness control, and 64 steps of constant-current scaling (SL).

SL can adjust brightness deviation between channels.

Features

  • VCC= 3.0V to 5.5V.
  • 24 current sink output channels tolerate up to 16V, multiple LEDs can be connected in series.
  • Support 24 current sink output channels and sink current capability with CB and GCC - 51mA (VCC≥ 3.2V, CB= “111”) - 37.5mA (VCC< 3.2V, CB= “101”).
  • Maximum Current Band (CB) - 3 bits (8 steps) with a 9.1% to 100% range.
  • DC Current Scaling (SL) - 6 bits (64 steps) with a 25.9% to 100% range.
  • Individual 16-bit, 8+8-bit dithering, 8+4.

IS32FL3268 24-CHANNEL, 16-BIT PWM LED DRIVER GENERAL DESCRIPTIONS The IS32FL3268 is a 24-channel constant current LED driver. Each channel has 16-bit PWM brightness control, and 64 steps of constant-current scaling (SL). SL can adjust brightness deviation between channels. GCC can adjusts brightness deviation between the R, G, and B color groups. The 8 steps maximum current band control (CB) selects the maximum output current range for all channels. Proprietary programmable algorithms are used in IS32FL3268 to minimize audible noise that can result from MLCC decoupling capacitor. SL, GCC, CB and all other registers can be programmed via a highspeed VSB (video series bus, up to 20MHz) or SPI (up to 20MHz) serial interface port.
