AAT3340 - High Efficiency 1x/1.5x Charge Pump

General Description

The AAT3340 is a low-noise, constant-frequency charge pump DC/DC converter that uses a dual-mode load switch (1x) and fractional (1.5x) conversion to maximize efficiency for white LED applications.

The AAT3340 is capable of driving 4 white LEDs at a total of 80mA from a single 2.7V to 5.5V input.

Key Features

  • Dual-Mode (1x/1.5x) Charge Pump.
  • Drives up to 4-Channel Backlight LEDs.
  • 32-Level Programmable Backlight Current (linear, inverting).
  • Single-wire S2Cwire Control.
  • Built-in Thermal Protection.
  • Automatic Soft Start.
  • -40°C to +85°C Temperature Range.
  • TSOPJW-12 and TDFN33-12 Packages General.
