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. The current sinks may be operated individually or in parallel while driving higher-current LEDs. A low external parts count (two 1µF flying capacitors and two small 1µF capacitors at.

PRODUCT DATASHEET www.DataSheet4U.com AAT3340 TM ChargePump High Efficiency 1x/1.5x Charge Pump 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 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. The current sinks may be operated individually or in parallel while driving higher-current LEDs. A low external parts count (two 1μF flying capacitors and two small 1μF capacitors at VIN and VOUT) makes the AAT3340 ideal for small battery-powered applications. Analogic Tech’s Simple Serial Control (S2Cwire) digital interface is used to enable, disable and set current to one of 32 levels for the LEDs. The AAT3340 is equipped with built-in short-circuit and over-temperature protection. The soft-start circuitry prevents excessive inrush current at start-up and mode transitions. The AAT3340 family is available in Pb-free, space-saving TSOPJW and TDFN33 packages, and operates over the -40°C to +85°C ambient temperature range. Applications • • • • • • Cellular and Smart Phones D.
