SY8805A Description
The SY8805A is a high-efficiency 1 MHz synchronous step-down DC-DC regulator, Current Mode Control IC capable of delivering up to 5A output current. The SY8805A operates over a wide input voltage range from 3V to 5.5V. It integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
SY8805A Key Features
- Low RDS(ON) for internal switches (top/bottom): 35/15 mohm

- 1 MHz switching frequency minimizes the external
- Internal softstart limits the inrush current
- Up to 98% efficiency
- 0.6V reference voltage
- Shutdown mode draws<0.1uA supply current
- 100% dropout operation
- Power good indicator
- OVP/OCP/UVLO/OTP protections
