IS32FL3265B - 18-CHANNEL LED DRIVER

Datasheet Summary

Description

The IS32FL3265B is an LED driver with 18 high voltage (40V) constant current channels.

Each channel can be pulse width modulated (PWM) by 8 bits for smooth LED brightness control.

Features

  • 3V to 5.5V operating supply.
  • Output current capability and number of outputs: 60mA × 18 outputs, tolerance voltage 40V.
  • 12MHz SPI with automatic address increment.
  • Programmable H/L logic: 1.4V/0.4V, 2.4V/0.6V.
  • Accurate Color Rendition - 32 steps Global current adjust - 8-bit Dot correction for each channel - 8-bit PWM for each channel.
  • Selectable PWM method (200Hz or 25kHz).
  • 256-Step group blink with frequency programmable from 24Hz.

IS32FL3265B HIGH-VOLTAGE, 18-CHANNEL LED DRIVER GENERAL DESCRIPTION The IS32FL3265B is an LED driver with 18 high voltage (40V) constant current channels. Each channel can be pulse width modulated (PWM) by 8 bits for smooth LED brightness control. In addition, each channel has an 8-bit output current control register which allows fine tuning of the channel current for rich RGB color mixing, e.g., a pure white color LED application. The maximum output current of each channel is designed to be 60mA, which can be adjusted by one 32 steps global control register. Proprietary algorithms are used in IS32FL3265B to minimize audible noise caused by the MLCC decoupling capacitor. All registers can be programmed via 12MHz SPI interface.
