AAT3195 - 4-Channel Charge-Pump LED Driver

General Description

The AAT3195 is a charge-pump based, current-sink white LED driver capable of driving one to four LEDs up to 30mA, each.

It automatically switches between 1x mode and 2x mode to maintain the highest efficiency and optimal LED current accuracy and matching.

Key Features

  • Drives up to 4 LEDs at up to 30mA, each Automatic Switching Between 1x and 2x Modes 1MHz Switching Frequency Linear LED Output Current Control.
  • Single-wire, S2Cwire™ Interface.
  • AAT3195-1: 30mA, 32-step.
  • AAT3195-2: 20mA, 32-step.
  • ON/OFF or PWM Interface.
  • AAT3195-3 ±10% LED Output Current Accuracy 3% LED Output Current Matching Low-current Shutdown Mode Built-in Thermal Protection Automatic Soft-start 2x2.1mm SC70JW-10 Pa.
