SY20321 Overview
Description
The SY20321 is a dual output, high efficiency 2MHz synchronous step down DC/DC regulator capable of delivering up to 2A output current for each output channel. The SY20321 operates over a wide input voltage range from 2.5V to 5.5V and integrates a main switch and a synchronous switch with very low RDS(ON) to minimize the conduction loss.
Key Features
- 2.5V to 5.5V Input Voltage
- 2MHz Switching Frequency
- 180°Out of Phase Operation
- Output Current: 2A per Channel
- Low Quiescent Current: <45µA for Both Channels
