SY20218 Datasheet | Silergy

Description SY20218 is a high-efficiency 1 MHz synchronous stepdown DC/DC regulator capable of delivering up to 6A output current. SY20218 operates over a wide input voltage range from 2.7V to 5.5V and integrates the main switch and the synchronous switch with very low RDS(ON) to minimize the conduction losses. Low output voltage ripple and small external inductor and capacitor sizes are achieved with 1MHz switching frequency.
