Overview
PRODUCT DATASHEET AAT2783 SystemPowerTM Triple Output PMIC: Dual Buck with Low-VIN LDO General Description Features The AAT2783 provides three independently regulated DC outputs: two step-down (Buck) regulators and a single low input voltage, low drop-out (LDO) regulator.
The input voltage range for the step-down regulators is 2.
7V to 5.
5V, while the LDO regulator allows inputs from 1.
5V to 5.
5V.
The low input voltage LDO regulator allows high efficiency, step-down, low noise outputs.
In addition, the LDO input may be connected to step-down outputs 1 or 2.
The Channel 1 and 2 step-down regulators can deliver up to 1000mA and 400mA output current, respectively.
Step-down output voltages are set with external resistors.
Switching frequency is set at 1.
3MHz to ensure small external filtering components.
Current mode control assures fast transient response and stable operation across the operating range.
The Channel 3 LDO regulator can deliver up to 400mA with -80dB power supply rejec...
