AAT2513 Dual 600mA Step-Down Converter with Synchronization General Description The AAT2513 is a high efficiency dual synchronous step-down converter for applications where power efficiency, thermal performance and solution size are critical. Input voltage ranges from 2.7V to 5.5V, making it ideal for systems powered by single-cell lithium-ion/polymer batteries. Each converter is capable of 600mA output current and has its own enable pin. Efficiency of the converters is optimized over full load range. Total no load quiescent current is 60µA, allowing high efficiency even under light load conditions. The integrated power switches are controlled by pulse width modulation (PWM) with a 1.7MHz typical switching frequency at full load, which minimizes the size of external components.
