SY8089AAAC power management IC
High Efficiency 5.5V, 2A, 3A Peak, 1MHz Continuous Synchronous Buck Regulator
SY8089AAAC Overview
The SY8089 and SY8089A are high efficiency, high frequency synchronous step-down DC-DC regulator ICs capable of delivering up to 2A of output current. The SY8089 and SY8089A operate over a wide input voltage range of 2.7V to 5.5V and integrate main and synchronous switches with very low RDS(ON) to minimize conduction losses. Low output voltage ripple and small external inductor and capacitor sizes are achieved at switching frequencies greater than 1MHz. The SY8089 integrates short-circuit and over-voltage protection with latch shutdown.
