AAT1160中文资料12V, 3A Step-Down DC/DC Converter数据手册Skyworks规格书

描述 Description

The AAT1160 is an 800kHz high efficiency step-down DC/DC converter. With a wide input voltage range of 4.0V to 13.2V, the AAT1160 is an ideal choice for dual-cell Lithium-ion battery-powered devices and mid-power- range regulated 12V-powered industrial applications. The internal power switches are capable of delivering up to 3A to the load.
The AAT1160 is a highly integrated device, simplifying system-level design. Minimum external components are required for the converter.
The AAT1160 optimizes efficiency throughout the entire load range. It operates in a combination PWM/Light Load mode for improved light-load efficiency. It can also operate in a forced Pulse Width Modulation (PWM) mode for easy control of the switching noise as well as faster transient response. 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 AAT1160 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.
