Description

The AAT2512 is a member of AnalogicTech's Total Power Management IC™ (TPMIC™) product family. It is a dual channel synchronous buck converter operating with an input voltage range of 2.7V to 5.5V, making it ideal for applications with singlecell lithium-ion/polymer batteries.

Both regulators have independent input and enable pins. Offered with fixed or adjustable output voltages, each channel is designed to operate with 27A (typical) of quiescent current, allowing for high efficiency under light load conditions.

The AAT2512 requires only three external components (CIN, COUT, and LX) for each converter, minimizing cost and real estate. Both channels are designed to deliver 400mA of load current and operate with a switching frequency of 1.4MHz, reducing the size of external components.

The AAT2512 is available in a Pb-free, 12-pin TDFN33 package and is rated over the -40°C to +85°C temperature range.
