AAT1161

PRODUCT DATASHEET AAT1 161 SwitchRegTM General Description The AAT1161 is an 800kHz high efficiency step down DC-DC converter with wide input voltage range. With 4.0V to 13.2V input rating, the AAT1161 is the perfect choice for 2-cell Li+ battery powered devices and mid power range regulated 12V powered applications. The internal power switch is capable of delivering up to 3A load current. www.DataSheet4U.com 13.2V Input, 3A Step-Down Converter Features Input Voltage Range : 4.0V to 13.2V Up to 3A Load Current Fixed or Adjustable Output: ▪ Output Voltage: 0.6V to VIN Less than 1μA Shutdown Current Up to 95% Efficiency Integrated High-Side Power Switch External Schottky Rectifier 800kHz Switching Frequency Soft Start Function Short-Circuit and Over-Temperature Protection Minimum External Components Tiny 14-pin 3x3mm TDFN Package Temperature Range: -40°C to +85°C The AAT1161 is a highly integrated device in order to simplify system level design for the users. It is a nonsynchronous converter that is used with an external Schottky diode rectifier for low-cost applications. Minimum external components are required for the converter. All the control circuits are integrated in the IC. The AAT1161 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 fast...
