概述
Description
The AW9967DNR is a high-performance, low-power DC-DC buck converter from Awinic, designed for applications requiring efficient voltage regulation.
Key Features:
- Input Voltage Range: 2.7V to 5.5V
- Output Voltage: Adjustable (e.g., 0.6V to VIN)
- High Efficiency: Up to 95% (PWM mode)
- Low Quiescent Current: ~25μA (light load)
- Switching Frequency: 1.5MHz (fixed)
- Protections: Overcurrent, overvoltage, thermal shutdown
Applications:
- Portable devices (smartphones, wearables)
- IoT sensors
- Battery-powered systems
The AW9967DNR integrates synchronous rectification for reduced power loss and supports PWM/PFM modes for optimal efficiency across load conditions. Its compact package (e.g., DFN-6L) makes it suitable for space-constrained designs.
For detailed specs, refer to the Awinic datasheet.
