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 AAT2513 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 60A, allowing high efficiency even under light load conditions.
The integrated power switches AAT2513 are controlled by pulse width modulation (PWM) with a 1.7MHz typical switching frequency at full load, which minimizes the size of external components. Fixed frequency,low noise operation can be forced by a logic signal on the MODE pin. Furthermore, an external clock can be used to synchronize the switching frequency of both converters.
A phase shift pin (PS) is available to operate the two converters 180 out of phase at heavy load test achieve low input ripple.
The AAT2513 is available in a Pb-free, thermally enhanced 16-pin QFN33 package and is specified for operation over the -40C to +85C temperatu range.
