Description
The SY8113I is a high efficiency, 500kHz synchronous step-down DC/DC regulator capable of delivering up to 3A load current.
It can operate over a wide input voltage range from 4.2V to 18V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
Features
- Low RDS(ON) for Internal Switches (Top/Bottom): 80mΩ/40mΩ.
- 4.2-18V Input Voltage Range.
- 3A Output Current Capability.
- 500kHz Switching Frequency Minimize the
External Components.
- Stable with 10µF COUT and 2.2µH Inductor.
- Instant PWM Architecture to Achieve Fast
Transient Responses.
- Internal Soft-start Limits the Inrush Current.
- Cycle-by-cycle Peak/Valley Current Limitation.
- Hic-cup Mode Output Short Circuit Protection.
- Thermal Shutdown with Auto.
