Description
The SY8003 and SY8003A are high-efficiency, high frequency synchronous step-down DC-DC regulator IC capable of delivering up to 3A output current.
Features
- 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 ope.
