AAT2688
Overview
The AAT2688 provides two independently regulated DC outputs: a high voltage synchronous step-down (Buck) regulator and a low input voltage step-down low dropout (LDO) regulator. The PMIC is optimized for low cost 12V adapter inputs, making the device the ideal system-ona-chip power solution for consumer communications equipment.
- 2-Output Step-Down Converters:
- Channel 1 (Buck): VIN1 = 6.0 to 24.0V; VOUT1 Adjustable from 0.8V to 5.5V; IOUT1 up to 4.5A; High Switching Frequency; Voltage Mode Control; High Accuracy ±1.5%; PWM Fixed Frequency for Low Ripple
- Channel 2 (LDO): VIN2 = 2.7V to 5.5V; IOUT2 up to 600mA; 1V Dropout Voltage at 600mA IOUT
- Small Solution Size
- System on a Chip
- Ultra-small External L/C
- Shutdown Current <35μA
- Independent Enable Pins
