描述 Description
Please note: this product is being discontinued and is not recommended for new designs.
The AAT3166 is a low noise, constant frequency charge pump DC/DC converter that uses a tri-mode load switch (1X), fractional (1.5X), and doubling (2X) conversion to maximize efficiency for white LED applications. The AAT3166 is capable of driving four LEDs for a total of 108mA from a 2.7V to 5.5V input. The current sinks may be operated individually or in parallel for driving higher current LEDs. A low external parts count (two 1μF flying capacitors and two small 1μF capacitors at VIN and VOUT) make this part ideally suited for small battery-powered applications.
AnalogicTech's AS2Cwire? (Advanced Simple Serial Control?) serial digital input is used to enable, disable, and set current for each LED with a 16-level logarithmic scale plus four low-current settings down to 115μA. For optimized efficiency, low-current mode settings require only 50μA of housekeeping current.
Each output of the AAT3166 is equipped with built-in protection for VOUT short-circuit and auto-disable for load short-circuit conditions. Built-in soft-start circuitry prevents excessive inrush current during start-up. A low-current shutdown feature disconnects the load from VIN and reduces quiescent current to less than 1μA.
The AAT3166 is available in a Pb-free, space-saving, 3x3mm 12-pin TDFN package and is rated over the -40°C to +85°C temperature range.
Please note: AAT3166 is not recommended for new designs.
