AX5524-1.2MHz 1.6A Output Current Boost Converter


AX5524-1.2MHz 1.6A Output Current Boost Converter DataSheet

GENERAL DESCRIPTIONG
    The AX5524 is a high efficiency current-mode boost converter with a fixed operation frequency. The AX5524 integrates a very low Rds-on NMOSFTET to reduce power loss and achieve high efficiency. The maximum efficiency is up to 93%. AX5524 can output 1.6A current when VIN is higher than 3.3V and output is 5V. 1.2MHz operation frequency minimizes L and C value, and internal compensation network reduces external component counts. SOT-23-6L package provides the best solution for PCB layout area.

FEATURES
- Wide Input Range: 2.5V to 5V
- Maximum Output: 8V
- Up to 1.6A output Current 
- 1.2MHz switching Frequency
- Low RDS (ON): 80mΩ 
- Up to 93% Efficiency
- Under-Voltage Lockout Protection
- Over-Temperature ProTemperature
- Internal Soft Start
- 1uA Shutdown Current
- Accurate Reference: 0.6V Voltage Reference
