SY20121 Overview
Description
SY20121 is a high efficiency 2.0MHz synchronous step down DC/DC regulator capable of delivering up to 1.5A output currents. It can operate over a wide input voltage range from 2.6V to 5.5V and integrate main switch and synchronous switch with very low RDS (ON) to minimize the conduction loss.
Key Features
- 2.6~5.5V Input Voltage Range
- 55µA Low Quiescent Current
- Ultra Fast Load Transient Speed
- Low RDS(ON) for Internal Switches (Top/Bottom) 180mΩ /100mΩ
- High Switching Frequency 2.0MHz Minimizes the External Components
