High Efficiency 2A continuous, 3A peak 1MHz Synchronous Step Down Regulator SY8089A SOT23-5

Beschrijving

used to repair Orange Pi Zero boards

The SY8089 and SY8089A are high-efficiency, high
frequency synchronous step-down DC-DC regulator IC
capable of delivering up to 2A output current. The
SY8089 and SY8089A operate over a wide input
voltage range from 2.7V to 5.5V and integrate main
switch and synchronous switch with very low RDS(ON)
to minimize the conduction loss.
Low output voltage ripple and small external inductor
and capacitor sizes are achieved with greater than
1MHz switching frequency.
SY8089 integrates short circuit and over-voltage latch
