Skyworks AAT1162

Description

The AAT1162 is an 800kHz high efficiency step-down DC/DC converter. With a wide input voltage range of 4.0V to 13.2V, the AAT1162 is an ideal choice for dualcell Lithium-ion battery-powered devices and mid-power- range regulated 12V-powered industrial applications The internal power switches are capable of delivering up to 1.5A to the load.

The AAT1162 is a highly integrated device, simplifying system-level design. Minimum external components are required for the converter.

The AAT1162 optimizes efficiency throughout the entire load range. It operates in a combination PWM/Light Load mode for improved light-load efficiency. The high switching frequency allows the use of small external components.The low current shutdown feature disconnects the load from VIN and drops shutdown current to less than 1μA.

The AAT1162 is available in a Pb-free, space-saving, thermally-enhanced 16-pin TDFN34 package and is rated over an operating temperature range of -40°C to +85°C.
