SY8003
Overview
The SY8003 and SY8003A are high-efficiency, high frequency synchronous step-down DC-DC regulator IC capable of delivering up to 3A output current. The SY8003 and SY8003A operate over a wide input voltage range from 2.7V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
- Low RDS(ON) for internal switches (top/bottom):110mΩ/80mΩ
- 3A continuous load current capability
- 2.7-5.5V input voltage range
- High switching frequency minimizes the external components: 1MHz
- Internal softstart limits the inrush current
- Reliable short circuit protection: SY8003: Latch off protection SY8003A: Hic-cup mode protection
- Reliable over-voltage protection: SY8003: Latch off protection SY8003A: No latch off protection
- 100% dropout operation
- RoHS Compliant and Halogen Free
- Compact package: DFN2X2-8.
