SY80003E
Overview
The SY80003E high efficiency 2.2MHz synchronous buck converter operates over a wide input voltage range of 2.5V to 5.5V, and can deliver an output current up to 3A. It integrates a top MOSFET and a bottom MOSFET with very low RDS(ON) to minimize conduction loss.
- Low RDS(ON) for Internal MOSFETs: 38mΩ Top, 30mΩ Bottom
- Wide Input Voltage Range: 2.5V ~ 5.5V
- Up to 3A Output Current
- ±1% 0.6V Reference over Temperature from -40°C to 125°C
- 2.2MHz High Switching Frequency Minimizes the External Components
- Advanced Constant On-time and Ripple-Based Control to Achieve Fast Transient Responses
- Forced Continuous Conduction Mode (FCCM) Operation
- Internal Soft-Start Limits the Inrush Current
- 100% Dropout Operation
- Power Good Indicator
