Application Note: SM8082A
High Efficiency, 1.5MHz, 2A
Synchronous Step Down Regulator
`
General Description Features
The SM8082A is a high efficiency 1.5MHz 2.5V to 5.5V Input Voltage Range
synchronous step down DC/DC regulator, which is 70μA Low Quiescent Current
capable of delivering up to 2A output current. It can Low RDS(ON) for Internal Switches (Top/Bottom)
operate over a wide input voltage range from 2.5V to 130mΩ /90mΩ
5.5V and integrate main switch and synchronous High Switching Frequency 1.5MHz Minimizes
switch with very low RDS(ON) to minimize the the External Components
conduction loss.
Internal Soft-start Limits the Inrush Current
The low output voltage ripple, the small external 100% Dropout Operation
inductor and the capacitor sizes are achieved with Hic-cup for Short Circuit Protection
1.5MHz switching frequency. Output Auto Discharge Function
RoHS Compliant and Halogen Free
Ordering Information Compact Package: SOT23-5
