General Description
The SY8031 is a high-efficiency 2.25MHz synchronous step-down DC-DC converter capable of delivering 1.2A output current.
SY8031 operates over a wide input voltage range from 2.5V to 5.5V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
Key Features
- low Rds(on) for internal switches (top/bottom): SY8031L: 300mΩ/200 mΩ, 0.6A SY8031: 200mΩ/150 mΩ, 1.2A continuous,2A peak.
- 2.5-5.5V input voltage range.
- 2.25MHz switching frequency.
- 100uA quescient current.
- Internal softstart limits the inrush current.
- 1.5% 0.6V reference.
- 100% dropout operation.
- Compact package: SOT23-5.
