概要
Description
- 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.
Equivalent
- MP2307 (Monolithic Power Systems)
- AP3416 (Diodes Incorporated)
- RT8059 (Richtek)
- TPS54331 (Texas Instruments)
These chips offer similar specs (e.g., input voltage range, output current, efficiency) and pin compatibility in most cases. Verify datasheets for exact replacements.
Pinout
Pin Functions:
1. VIN (Pin 1): Power input (2.5V–5.5V).
2. GND (Pin 2): Ground.
3. EN (Pin 3): Enable control (high = on, low = off).
4. FB (Pin 4): Feedback for output voltage regulation.
5. SW (Pin 5): Switching node (connects to inductor).
6. PG (Pin 6): Power-good indicator (open-drain output).
Key Features:
- Output current: 1A
- Adjustable output voltage (0.6V–VIN).
- High efficiency (up to 95%).
Compact and efficient, it’s ideal for portable devices.
