1 / 16 page  SwitchReg™ AAT1154 1MHz 3A Step-Down DC/DC Converter 1154.2006.09.1.6 1 General Description The AAT1154 SwitchReg is a step-down switching converter ideal for applications where high efficien- cy, small size, and low ripple are critical. Able to deliver 3A with an internal power MOSFET, the cur- rent-mode controlled IC provides high efficiency. Fully internally compensated, the AAT1154 simpli- fies system design and lowers external parts count. The AAT1154 is available in a Pb-free SOP-8 pack- age and is rated over the -40°C to +85°C tempera- ture range. Features •VIN Range: 2.7V to 5.5V • Fixed or Adjustable VOUT: 1.0V to 4.2V • 3A Output Current • Up to 95% Efficiency • Integrated Low On Resistance Power Switch • Internally Compensated Current Mode Control • 1MHz Switching Frequency • Constant Pulse Width Modulation (PWM) Mode • Low Output Ripple With Light Load • Internal Soft Start • Current Limit Protection • Over-Temperature Protection • SOP-8 Package • -40°C to +85°C Temperature Range Applications • Cable/DSL Modems • Computer Peripherals • High Efficiency Conversion from 5V or 3.3V Supply • Network Cards • Set-Top Boxes Typical Application OUTPUT INPUT 1.5 μH 120 μF LX VP FB GND AAT1154 VCC EN 10 μF 0.1 μF 100 Ω |
