SY20193L
Description
SY20193Lis a highefficient1.0MHz synchronous step down DC/DC regulator capable of delivering up to 3A output current. The SY20193Lcan operate over a wide input voltage range from 2.7V 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) 85mΩ /50mΩ
- 2.7~5.5V Input Voltage Range
- 55µA Low Quiescent Current
- Ultra Fast Load Transient Speed
- High Switching Frequency 1.0MHz Minimizes the External Components
- Internal Soft-start Limits the Inrush Current
- Reliable Latch off Function When:
- Output Short
- Thermal Shutdown
- Output Voltage> 120% of Regulated Voltage
