SY20313A
Description
The SY20313A is a dual-output, high efficiency 2MHz synchronous step down DC-DC regulator IC, capable of delivering up to 1A output current each output channel. The SY20313A operates over a wide input voltage range from 2.5V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
