AW9967DNR

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.

The AW9967DNR is manufactured by Awinic, a Chinese semiconductor company specializing in analog and mixed-signal ICs. Awinic focuses on power management, audio amplifiers, LED drivers, and other consumer electronics components. Established in 2008 and headquartered in Shanghai, the company serves global markets with cost-effective solutions for smartphones, IoT devices, and wearables. It is known for its competitive pricing and integration capabilities but is not as prominent as industry leaders like Texas Instruments or Qualcomm.

The AW9967DNR is a battery protection IC primarily used in:
1. Lithium-ion Battery Packs – Ensures safe charging/discharging.
2. Portable Electronics – Smartphones, tablets, and wearables.
3. Power Tools & E-Bikes – Protects high-current battery systems.
4. Energy Storage Systems – Solar-powered and backup battery management.
5. Medical Devices – Safeguards battery-operated equipment.
It features overcharge, over-discharge, and short-circuit protection, making it essential for battery safety and longevity.

The AW9967DNR is available in a DFN-8 (2x2) package, which is a small, leadless, surface-mount type. This compact package is suitable for space-constrained applications, offering good thermal and electrical performance. The dimensions are typically 2mm x 2mm with a height of 0.75mm.
