General Description
The SY8104I is a high efficiency 500kHz synchronous step-down DC/DC regulator, which is capable of delivering up to 4A 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.
Key Features
- Low RDS(ON) for Internal Switches (Top/Bottom): 55mΩ/36mΩ.
- 4.2-18V Input Voltage Range.
- 4A Output Current Capability.
- 500kHz Switching Frequency Minimize the External Components.
- Stable with 22µF COUT and 0.68µH 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 Aut.
