SY20011B Overview
Key Specifications
Description
The SY20011B is a 400nA ultra low quiescent current, 1.0MHz synchronous step down DC/DC regulator, which is capable of delivering up to 500mA output current. It can operate over a wide input voltage range from 2.0V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
Key Features
- 2.0~5.5V Input Voltage Range
- Ultra Low Quiescent Current Down to 400nA
- Low RDS(ON) for Internal Switches (Top/Bottom) 280mΩ /120mΩ
- Instant PWM Control to Achieve Ultra Fast Load Transient Speed
- High Switching Frequency 1.0MHz Minimizes the External Components
