Overview
Description
The SY8089AAC is a high-efficiency, synchronous step-down DC-DC converter designed for portable and battery-powered applications. Key features include:
- Input Voltage Range: 2.7V to 5.5V
- Output Current: Up to 2A
- High Efficiency: Up to 95% (PWM mode)
- Low Quiescent Current: 22μA (typical)
- Adjustable Output: 0.6V to VIN (via external resistors)
- Fixed Switching Frequency: 1.5MHz
- Protections: Overcurrent, thermal shutdown, and undervoltage lockout (UVLO)
The compact 1.5mm × 1.6mm DFN package makes it ideal for space-constrained designs like smartphones, tablets, and IoT devices. It operates in PWM mode for consistent performance under load and supports 100% duty cycle for dropout conditions.
Applications:
- Portable electronics
- Battery-powered devices
- Point-of-load (POL) regulation
The SY8089AAC balances efficiency, size, and cost, making it a versatile choice for low-power voltage regulation.
