Description
The RT4822 allows systems to take advantage of new battery chemistries that can supply significant energy when the battery voltage is lower than the required voltage for system power ICs.
Features
- Ultra-Low Operating Quiescent Current.
- Quickly Start-Up Time (< 400sec).
- Few External Components Required: 1H
Inductor, 0402 Case Size Input and 0603 Case Size Output Capacitors.
- Input Voltage Range: 1.8V to 5.5V.
- Programmable Output Voltage from 3.15V to 5.5V with 25mV/Step.
- Support VIN > VOUT Operation.
- Default Boost Output Voltage Setting: VOUT = 5V.
- Maximum Continuous Load Current: 1.5A at VIN > 3.6V Boosting VOUT to 5V.
- Up to 93% Efficiency.
